while JS its <= either one of them

i think thats the case

im not sure im checking the documentation

[idle dew]

Hi, someone who know about java, to help me in a school proyect

[hidden forum]

for if statements theya re the same, but for while monka

[strange zodiac]

wait i think i sent you wrong screenshots when i tried it

i had the console.log() before it adds 2 for the while

[hidden forum]

that would mean that the while loop in JS does not require an iteration statement

hmm

forget what i said, that was a stupid comment lmao

[strange zodiac]

nah im stupid as well

its night alr i cant think

[hidden forum]

var x = 0;
while(x < 12) {
console.log(x);
x = x + 2;
};
//output 12

js in a nutshell

is 12 < 12

it isnt

int x = 0;
while(x < 12) {
  std::cout << x << std::endl;
x = x + 2;
};
//output 10

[strange zodiac]

wait i retract my earlier statement

[hidden forum]

😄

looking from a different angle

i cant see it any different than JS while loops initalize first

c++ while loops check first

i mean cant see it any different rn

[strange zodiac]

since it prints it in the console first. imagine that it just printed x=12. it should then add 2 to 12 making it 14 but it shouldnt print 14 anymore since going back to the top of the while loop 14 > 12

[hidden forum]

im walking away from the problem now

i cant get stuck for another hour i dont want to hehe

[strange zodiac]

but it does make sense logically right?

XD

[hidden forum]

thankyou for taking the time out of your day

no my mental block is strong hehe i dont get it

i agree with c++

bc im like you are comparing left side with the right side

[hidden forum]

KEKW

im done

@strange zodiac think i got the winning answer here

[strange zodiac]

wait what

🤯

i think it just prints out that 14

for some reason

yeah its just the browser console that i was using

when i do it here its only up to 12 but in the console it shows 14 but with that arrow

[hidden forum]

so the browser is the peace of shite then

piece*

@strange zodiac

[strange zodiac]

but why were you getting 14

[hidden forum]

i am using replit

https://replit.com/languages/nodejs

[strange zodiac]

yeah idk why it shows 14 then 🤷‍♂️

[strange zodiac]

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/while

it shows up to 12 only

[hidden forum]

KEKW

im so done

browser be like

its 14

ide be like its 12

i swear i cba

[strange zodiac]

it should be 12

[hidden forum]

yes the ide on mdn web docs its 12

[strange zodiac]

we should have talked about this in a thread 😂

[hidden forum]

in the dev tools

its 14

yes i regret not doing it now 😢

problem solved it guess

[flat vale]

I'm working on a dynamic website and am having some issues

[strange zodiac]

yes

[deft badger]

Is there someone who knows how to help me in cisco packet tracer ? 😢

[scenic oriole]

yo anyone good with graphs and wants to help me understand a few algorithms better

im having trouble finding all possible cycles within an undirected graph that runs in O(|V| + |E|) and that I can understand lool

I know that you can detect that a graph has a cycle by running bfs on each node and seeing if you encounter another 'flagged' node while bfs is still running but i dont think this would help in any way

[dawn sail]

I know this was a while ago, but Javascript is asynchronous, meaning code doesn't execute in the order you write it, like C++, but it will execute multiple statements at the same time, and x being incremented executes faster than the print. Take a look into the await/async funcs

[scenic oriole]

Ive also found this article that talks about smth called johnsons algorithm but i cant understadn it for the life of me, heres the article (https://www.cs.tufts.edu/comp/150GA/homeworks/hw1/Johnson 75.PDF)

and the issue is I dont even know if johnsons algorithm can apply to undirected graphs :/

[hidden forum]

thankyou this is a great answer, i am not that far into JS but i wrote it down that when i come there i will pay extra attention to this

[red hare]

seems sus, i wouldn't trust this ^

can someone please help me im having a mental breakdown ive to code this stupid button in python and its supposed to open something and I cant im about to drop out

[mental flare]

could someone tell me whats wrong with this code

[verbal wraith]

you need to tell us what's the expected behaviour

and what's the actual behaviour

also error logs if there are any

"What's wrong" is very vague

[mental flare]

im trying to swap the words in the spans

but when i try the console says it cant read the properties of the .innerHTML

[idle dew]

Selected is always null. it is not initialise anywherr

[idle dew]

I instead of selected==0 do selected==null

[mental flare]

thank youuuu

[peak yacht]

does anyone know how to learn about gpu construction and how to modify gpu's bios?

[red hare]

nowadays most video card firmware is digitally signed

I dont think you cant mess with it like you want

You can however learn about it's construction yeah

I recomend looking at wikipedia articles since they usually start from the beginning of graphic cards, and it's easier to follow

You can program your GPU tho, but i don't think that's what you meant

You have langs for that, like CUDA and OpenCL

[peak yacht]

Thanks for help

[subtle heart]

Is this chat also for theoretical CS?

[soft summit]

This is Delphi, because APPTYPE CONSOOLE is only used in Delphi. Also funny to see Russian comments in the code

[agile sonnet]

I need help with these. using c++ stdio.h

[idle dew]

can someone help me with some simple codes? i'm new and i'm really confused🥺 😭

[bold shadow]

What's the problem

[red hare]

first of all, why are you using a C lib for standard input and outpu?

#include <iostream>

This is the one you want for standard IO in C++

Second, you will need access to the math lib

because you will need the square function and the root function

[agile sonnet]

sschool work

[red hare]

Still, doens't make sense to use C libs on C++ (unless that are no other alternatives)

[bold shadow]

https://www.w3schools.com/cpp/cpp_math.asp

[red hare]

#include <cmath>

This is the lib for math related function and constant values

the functions you are looking for are std::pow() and std::sqrt()

If you have any trouble using them just post here your question and we'll help, but they are pretty straight forward to use

[agile sonnet]

thanks thou. big help

[fresh solstice]

Can anybody which languages required for game development

[dusky oxide]

it depends entirely on what you want to create, youll have to see what programming language fits your needs

just a couple of examples (not going in-depth):

2d - python: python syntax is close to pseudo code making it easier to learn, plus it has the pygame library which is the most used 2d game making library in python. its popularity makes it easier to learn and solve problems.

-c#: c# can be used in the unity engine to create simple 2d games, the use of an engine is that it gives you a ton of features to work with. the unity community has a lot of tutorials and solutions so it is really and has a less steeper learning curve

3d - c++: c++ is a powerful low level language that communicates with the hardware with almost full capability. this makes games developed in it way faster although the low level aspect gives it a bigger learning curve (harder to learn). you can use the OpenGL library to communicate with your GPU to render stuff on the scree.

-c#: again, c# can be used to create 3d games in unity, with a ton of tutorial and a lot of help, learning unity "should" be pretty easy although i havent tried it so i cant give my full opinion on it

there are other programming languages that you can use such as java or javascript but i cant write about them as i dont have enough info about them (you could def research though!).

i hope this guides you in anyways and looking forward to see what you create!

[idle dew]

C# is widely used because of all the stuff thats available for it

[fallen steppe]

is there anyone who know matlab for numerical method. I need some help for function commend

[scenic oriole]

hey i wanna make an app, ik react and i heard react native was easy to learn, but i was wondering what backend i should use or if theres one that works well with react native

I saw online that ppl said to use firebase?? but ive never used it as a backend framework so idk lol and suggestions

the app is gonna be simple i just need to have like login, store some images, text thats all lool

[tidal violet]

Hey!
My uni offers me 2 courses as electives -

1. Internet of Things
2. Quantitative Analysis
   Can someone help me get a better idea about these subjects?
   Thanks in advance!

[strange zodiac]

wouldn't your uni have a course description of what you will be learning and exploring?

[verbal wraith]

This

[tidal violet]

Yea we've been give the syllabus and course outcomes for the same, but I'm still kinda confused :/

Like quantitative analysis is mostly stats and will be helpful if one's into data science
And IoT well you get to know more about hardware ig

I mainly want to know which one has greater scope in cs field or are they equally good..

[verbal wraith]

They are both quite useful in different fields

It depends on your domains of interest, which one you go for

[tidal violet]

Yes yes, I'll look into these subjects in detail, thanks for helping :)

[red hare]

Unless you're game dev'ing for XBox, I would stay away from C# honestly

I wouldn't consider game dev till you are taught the basics of OOP @fresh solstice

Else it will be kinda annoying

And if you are a beginner I would stay away from C++, C++ is not a language you just pick up and start game dev'ing in, it's really hard to grasp expecially when you are starting with such an advanced topic as game dev'ing

Python i think would be a nice starting point

Maybe look into the Unreal Engine, i think they have a script lang

UnrealScript yeah

Or Java maybe, but again OOP principles are a must in my opinion

[fresh solstice]

By the way, tell one thing is app development easy or gaming Development

[dusky oxide]

i dont understand what youre saying?
i listed some methods of game dev although some of these ways are hard and require you to create from scratch

[fresh solstice]

Thank you actually i am beginner .

[fresh solstice]

Okk.

[red hare]

Are you a beginner in programming?

[fresh solstice]

Yes I am beginner

[red hare]

Maybe stay away from game dev'ing till you learn a bit more of what exactly is programming

Start small

[dusky oxide]

you shouldnt really learn c++, it has a much higher learning curve.

[red hare]

Make small stuff, learn slow

Don't rush into a big things like game dev, in my opinion

Take your time learning the basics of programming first

[dusky oxide]

i wouldnt exactly say not to game dev, unless you dont know any of the basics such as OOP or arrays and such, you can make little 2d games. but you also should consider not creating big projects, work on what you are capable of

[red hare]

You could, except he's new to programming

[dusky oxide]

like 0% new?

[red hare]

Unless you're talking about Scratch, I would advice against starting like that

[fresh solstice]

what should i start first which language

[dusky oxide]

im not talking abt scratch but creating simple games would be a good learning experience, unless he is a total beginner just as you said

[dusky oxide]

as i said before, it depends on what you want to create

[red hare]

Do you have any experience with programming?

Have you ever programmed annything?

At all?

[fresh solstice]

NO

[red hare]

You shouldn't even be thinking about game deving then : )

[dusky oxide]

yeah you really shouldnt at this stage, pick up a PL and start learning the basics. you will get to learning game dev then

[red hare]

Are you a self learner?

Or do you have programming classes?

Actually, go to a library

[fresh solstice]

Okk thank you .if i start with the phyton

[red hare]

Grab a C book

or a Python book

and start from there

[fresh solstice]

Ya i am self learner .

[red hare]

So my advice is, get a book

Or find a book online, whatever suits you better

[dusky oxide]

actually i have nothing to say, this is the best thing you could get.
pick a PL, get a book for it and start learning

[fresh solstice]

If I take Udemy Course

[red hare]

You could do that... or you could get a book

I'd say you'd be better off with a book

[dusky oxide]

if you learn better from a udemy course, sure.
but i dont really know about the course youre choosing

[fresh solstice]

Okk thank you 🤗

[dusky oxide]

(a book is better than a course tho but np)

[red hare]

The reason why I'm more inclined for you to get a book is to force the habit of reading. If you want to be good at anything you will need to read

You will need to read documentation, hardware details, github projects, code, etc

Alot of people lack that

[dusky oxide]

plus books just give you more freedom and some times (depending on the book), gives you more detail.

[red hare]

The major problem with books is that once they are printed, you can't update what on the book

So alot of books that are printed stay deprecated as time goes by

Unless we are talking about like C or old languages

But usually for a beginner that's not really an issue

[dusky oxide]

still, even if the book is old, it provides a ton of information (Although yeah books may go too old)

[red hare]

Yeah, i'd still recommend a book, making people read is important

But also practise

Try to learn by try and error while you read

And don't be sad if you get errors

Every one get's errors

Errors are a regular occurrence in a programmer's life

Even the experts get errors, the only difference is that errors from experts usually can only be solved by other experts X)

Does anyone know where I can create a website easily? I'm supposed to code it but I don't know anything about coding

[void halo]

There is a bunch of different websites that you can use to create an online website. It really depends on to what extent you want it to look good. Also, if you are expected to code it you are going to have a tough job getting away with a nicely formatted pre-made sight that you just drag and drop things onto.

• Something to just consider?

[paper raft]

I am gonna be talkinf computer architechure next sem. Anyone take it yet and let me know what is the most difficult part about it.

[void halo]

Working with Assembly is difficult at first but once you get enough practice it becomes pretty simple honestly.

[paper raft]

I am learning MIPS RN.

I am almost done with it.

It is kinda cool learning about some of the components of the CPU and how the registers hold and store info.

[orchid pier]

anyone any good with C?

[idle dew]

This is weird, I just bought a T60 off Facebook Marketplace and it has a glossy screen, wasn't until I got home, I've realised it looks like a screen protector?

not too sure though

flash light it

I went for it and it was, well it came off so 🤷‍♂️, now just glue residue time

[visual sapphire]

I am deciding between choosing ipad m1 11' and 12.9' . 12.9' more than 11' $300 but only better at the screen. if i select 12.9' and paste paperlike on it, will the display quality drop much? if it's a lot, I should choose the 11' version right? please advise me which one to choose and type paperlike i should use

[verbal bone]

hi i need some help , In a system, which uses an ASCII code of 8-bits, how many pages one can store in hard disk space of 760 Mbytes. Suppose that each page contains 2000 characters.
-but ASCII only do about 256 characters i guess right ? 🥲
thank u

[void halo]

I have the 12.9 version but one of the older version right before m1 chip came out. I also have it with the paperlike screen protector. If you are going to be using the iPad for school then paperlike in my opinion is a must have amenity. If you are just using it for leisure then honestly any amazon screen protector will be fine.

The paperlike screen protector does not impact the display quality at all. It is truly just an amenity that makes looking at the iPad easier and increases the feel of the iPad when using it for writing.

[paper crest]

if you got a question just ask.

don't say "is anyone any good with C"

it's like saying "is there any expert around to help me out with my code"

https://dontasktoask.com/

[quiet vault]

For some reason i decided to open and no regrets ahah it makes a valid point tho

[paper crest]

🤷‍♂️

[quiet vault]

actually sometimes i dnt answer people when they make those sort of questions cause idk if i will be really able to help or not so yeah good advice people make ur questions clear

[paper crest]

it's like this everywhere, instead of asking the question they asking for "experts" to help them, even a beginner can help if they actually read what the problem is

[paper crest]

exactly

[quiet vault]

yeah

[verbal wraith]

I always feel like posting this here but I abstain cause it might be rude and because mostly people won't see it anyway :))

[quiet vault]

well i had never seen that before but it makes a lot of sense i think everyone should read it tbh

[paper crest]

in this case for him no one replied, ofc no one did no one is gonna call themselves an expert when they don't really know what the issue is

[quiet vault]

yeah

[paper crest]

it's not rude, if they read it in a rude way that's a them problem not mine

im just dropping it there so they can learn something 🤷‍♂️

im actually helping if you think about it 😉

[quiet vault]

well dnt get me wrong but do u know the answer to my question in maths by any chance?

[verbal wraith]

Apart from that, people often post questions without the relevant data associated with it

[paper crest]

no sorry i can't help you with that

[verbal wraith]

Like a screenshot of code and then "what's wrong with it" 😐

[quiet vault]

thx anyway!

[paper crest]

or they give you a log with 500 lines in it asking you to solve it for them

people should be specific when they ask question, when you ask a question you should give all the information needed for someone to help you out, you can't just say "help me with this"... What does the error say for example

[nova basin]

it abt computer system. like the components and its relation. its quite not easy cause its smth we dont see. its how computer work inside and stuff but once u grasp the concept, you'll be fine. it just full of theory to remember ❤️

[paper crest]

exactly what im saying 😂

yeah sure i'll just send my 300 lines of code to someone and make him read all that and see where the problem is like... just tell me where is the problem 😂

people doing that are making others life harder doing this..

[verbal wraith]

I mean, people just won't reply to that message for help

[paper crest]

actually, there's gotta be an error in the terminal, else if there is no error then it's fine 🤷‍♂️

[verbal wraith]

No one wants to go through lines of code to find an arbitrary problem

[paper crest]

no one wants to go over 100 lines of code just to find a typo

like me yesterday spending my whole day in 500 lines of code just to find out i did a typo...

pain

[quiet vault]

well im sorry to bother u guys but seems like u two both know a lot about coding do u have any tips on how to understand loops? im having a hard time deciding whether i should use while or do... while in c sharp. Totally fine if u dnt

[paper crest]

yeah not the best dude to ask for maths 😂 and imo you should ask in #math-help incase you didn't and if you did then i guess go try on https://mathpapa.com

[paper crest]

got the perfect vid for you

i'll send it

[quiet vault]

i did ask there but no one actually answered and im here with the book opened waiting for a generous soul to help me ahahah

[paper crow]

Basically is about wether you want your code to be executed first and then make the decision or vice versa

[paper crest]

🤣

[quiet vault]

thx its hard to apply in exercises tho

[paper crest]

what she is asking is when and what should be used for specific stuff

[quiet vault]

thank youu!

[paper crow]

I cannot send such a huge text, sry

[paper crest]

that's why im sending a video instead 🤷‍♂️

[quiet vault]

just tried they dnt know how to solve the inequality thx tho

[quiet vault]

totally fine! thx anyway

[paper crest]

there are a bunch of other websites to help you out with math

im pretty sure you can find other ones that work with a simple google search

[quiet vault]

u right i will try

[paper crest]

just type your problem and you might find it

[quiet vault]

yeah idk why i didnt think of that tbh mb

[paper crest]

no worries (:

[paper crow]

Happy learning!

[nova basin]

well. do...while is u do first then u loop. if while... u loop first then u print or do stuff

[paper crest]

she will understand better with the video im sending

[quiet vault]

ok thx everyone yall really helpful!

[red hare]

A loop is something that executes a piece of code until a condition is met

So that you don't have to type the same code N times, and if you don't know how many times to run the same piece of code for example

[quiet vault]

yeah thank you!!

[red hare]

What language btw?

[paper crest]

C#

[red hare]

sheesh

[quiet vault]

U think its hard?

[red hare]

Not at all!

I just dislike it : ) But don't let my experience influence you! Is a nice language for beginners and web stuff

[quiet vault]

Ah alright!!

[paper raft]

Thanks!

[paper crest]

C# isn't for web...

[alpine mesa]

hello everyone

[paper crest]

Hi

[alpine mesa]

hi

[paper crest]

Many others hate it aswell

[paper crest]

How's life?

[alpine mesa]

great how are ya

[paper crest]

Im good, still breathing yk :)

[alpine mesa]

😆

I have a bit of a boring question, is anyone in this group learning Assembly language?

[red hare]

What?

C# is used for ALOT of web stuff

It's a web language

[paper crest]

C#?

I don't see anyone making websites in c#

[red hare]

Inform yourself! 🙂

[alpine mesa]

not actually i think, but yeah c# is used many in web

[red hare]

Sure you can use if for non-web things, it's still a web language

[paper crest]

I think you misunderstood

[red hare]

Look at the API's for C#

[paper crest]

C# can be used for web applications

[red hare]

They are all web oriented

[paper crest]

Now for websites, i don't think that's the same

[red hare]

Whatever you say man

[paper crest]

Easy to start: C# is a high-level language so it is closer to other popular programming languages like C, C++, and Java and thus becomes easy to learn for anyone. Widely used for developing Desktop and Web Application: C# is widely used for developing web applications and Desktop applications.

[alpine mesa]

now you can code web by any language

[paper crest]

well you're not wrong, but at the same time you're not right

if you use frameworks maybe

well im not really sure, but i feel like C# can't be used to make websites

but maybe for web applications

well if you're using some kind of a framework then yes but you can't really build a website without any kind of a framework 🤷‍♂️

[quiet vault]

well i think it can be used for web but i im using it for "console"

[red hare]

that's usually how you start yeah

[quiet vault]

sadly i am still struggling with the exercises even though i understood the theory 🙃

[paper crest]

What is the excercise?

[paper crest]

Well idk c# but im curious

[quiet vault]

Product of a sequence of real numbers, ending with 0.

i guess it dsnt seem very hard

but i am having a hard time doing it

and so i just delayed studying for tmrw

this is an example

product is multiplication (*)

yeah idk how to help you with that

sorry 😦

[quiet vault]

oh np dnt worry!

[paper crest]

did you try google about your problem?

[quiet vault]

i didnt cause idk seems like a very specific problem

but i did some coding

~its just some stuff that is not correct

and idk how to put it

[paper crest]

is there an error?

[quiet vault]

double numero, b=0, multiplicação;

        Console.Write("\nNúmero? ");
        numero = Convert.ToDouble(Console.ReadLine());

        if (numero == 0)
            Console.Write("O produto dos números é 0.");
        else
        {
            while (numero != 0)
            {
                if (numero != 0)
                {
                    b =b+ numero;
                    multiplicação = 1.0*numero * b;
                
                    Console.Write("\nIntroduza um número: ");
                    numero = Convert.ToDouble(Console.ReadLine());
                }
                else   
                    Console.Write("\nO produto dos números é: {0}", multiplicação);
            }

i put this

but idk where to put the ahh idk how to say it in english, average i thinkk

not average

the multiplication

average was from the previous exercise

i will look at this again tmrw and try to figure it out tho

[paper crest]

well i can't see what's wrong

[quiet vault]

ah the multiplication i think its wrong and it lacks console.write ("The multiplication is equal to...") but i just dnt know where to put it

thx for trying to help tho

[paper crest]

i don't think you need to add this 1.0*numero * b

you can just do this instead 1.0 * numero

without the b

oh sorry

1.0 * b

without the numero

[quiet vault]

the thing is like that wont it just give me the last number i inserted? instead of the multiplication of all the numbers?

[paper crest]

you're already adding numero to b so i don't think there is a need to multiply them both again

[quiet vault]

hmm the thing is suppose i insert the numbers 5 and then 10 i will get b=0+5 and so b=5 then i insert 10 and i will get b=5+10 so b=15 that is different from 10*5 which is 50

[thin hound]

What exactly should the program do? Do you just keep entering numbers that will be multiplied until you enter 0?

[quiet vault]

yes that is it

[thin hound]

double new_number = 1;
double product = 1;
while (new_number != 0){
  // TODO: Ask for new number with Console.Write
  new_number = Convert.ToDouble(Console.ReadLine());
  if (new_number != 0)
    product = product * new_number;
}
// TODO: Write the product

You can try an approach like this

[quiet vault]

that looks way more simple thx i will try just a question in case the first number inserted is zero it should probably give a error message, how can i do that? do i put it inside a else under the if inside the while?

sorry if my message is kinda confusing

[quiet vault]

just tried it is working tysm

[thin hound]

Then you need to use an if to check for it.
Instead of double new_number = 1; in the first line, you can replace it with

Console.Write("Enter a number\n");
double new_number = Convert.ToDouble(Console.ReadLine());
if (new_number == 0)
  Console.Write("Enter a number other than zero \n");

[thin hound]

de nada

[quiet vault]

thx i will try it

Can someone help me with a little issue related to arrays in C?

[thin hound]

Not sure if anyone answered this already, but you could do a list of Nones, and then use it as an array. Then you should make a Class ListNode for your implementation of the linked list. If you haven't made a linked list in python before, then you should start there. If it is not important that you make the linked list yourself, and just need a list of empty lists, you can do list = [[] for _ in range(8)]

[thin hound]

what is the issue?

[thin hound]

you should try to express all components as the same base number:

the string gets a value but is not loaded into the database.

[strange zodiac]

i would put the $email=$_POST["email"] as well as $nome above the $sql variable

you are inserting $email into your query without setting its value

i also dont think you need the '' in the VALUES()

[idle dew]

I did a new test, apparently the problem is that the PHP code doesn't connect with the Email and Name columns

[strange zodiac]

Before you use a variable. You have to first create one and set a value

[idle dew]

I thought the order didn't matter xp

[paper crest]

it does actually

it's from top to bottom

you can't make a function and print a value that does not exist, you will get undefined, that happens for example if you put the variable below the function

if you put it above it does work (:

anyone pretty good at html? tyring to display data from a json file in a text field

I can display it in a text area but not text field for some reason

[strange zodiac]

are you assigning the the json data into the value attribute?

[rugged pasture]

Atm I was using AJAX to retrieve the JSON data by doing this

document.getElementById("bookID").innerHTML = (" " + Obj.books[i]["id"]);

Then in the HTML using id="bookID".

I couldnt get it to work for the text field, but it works for
<textarea id="bookID"
When I try to put anything for value inside of a text field, it'll display whatevers in the "" instead of bookID

[strange zodiac]

are you using both the text area and the text field? if so im pretty you cant have more than one element with the same ID

another possibility is that you should be using .value to assign to a input field
https://stackoverflow.com/questions/7609130/set-the-value-of-an-input-field

i just ran a test on w3schools idk if it helps or not

[red lily]

this is python, why does it come out has 84 and not 44

[scenic oriole]

use elif statements

when u use all if statements like that, they are all being checked one after another meaning one input could be true for multiple if statements, what u want is only one of those statements to be true and then u check the next input

change ur two inner if's to elifs and ur last one to an else and try again

[red lily]

thx

[rugged pasture]

I ended up using text area because text field was not working for me, but text field was preferred.

I will look at this when I am back at my computer, definitely seems like a great help. Ty ty

Don't think like that, you're not wasting anyones time, if people were annoyed and didn't wanna waste their time they wouldn't try to help, actually they shouldn't try to help, so don't say that again, if anyone wants to help they will and try to, if not they should not reply and move on with their days

thx for being friendly : )

[paper crest]

So if you need help just ask for it and if anyone is willing to good if not then they shouldn't reply 🤷🏻‍♂️

No worries :)

If I have a group of text fields say named 1-5, that I want to edit all at once (toggle on/off the text field)
can I just put them in a div class and make one button that allows that toggle? instead of making an individual button for every text field.

[strange zodiac]

you can still use ID's for them with only 1 button. You will need to create a click event function that gets all 5 ID's. But yes you can use CLASS for them. I would still keep the separate ID's for each text field for any possible features that involves 1 text field.

Can I ask why you want to do that? stdio is used in C mostly and has less features than iostream, which is made for c++

[red hare]

just replace the cout's with printf's, and the cin's with scanf's

For example

cout << "Initial array:" << endl;

becomes

printf("Initial array:\n");

Read the documentation for printf or scanf, it will explain in detail how to use them

I had a lot of trouble finding internships and jobs by just randomly applying. A lot of getting a job is about connections, so try going to job fairs etc on campus and talk to your professors about opportunities. My university had a company that recruits a lot of our students and that is how I got my opportunities.

[strange zodiac]

i have it on. i wouldnt say its cheesy tho 😂

[strange zodiac]

i would go with informational interviews. i recently just learned about them at school and we were able to practice it as a project. It is a good way to connect and learn more about the industry in the area you are interested in. I wouldnt say that doing these will get you jobs directly but it does build your network. if you stand out they might connect you with people they know who they know who has a spot for you.

just check if it's >= 0 i guess?

I dont really think there is a built in functionality for that

you could make a function to check it

bool isNatural(int number)
{
  return (num >= 0);
}

I did that but i though i had to make sure the given number wasnt like 2.3 or something but then i asked the teacher and actually it just couldnt be a negative number or zero the question was badly written thi

$max = 0
foreach ($data in $file) {
  $k1, $k2, $date, $t, $count = $data -split ' '

  if ($count -gt $max) 
  {
  $max = $count

hello I just started learning java, does anyone know why the output of my code is 98 when i equate int a to 'b' even tho int b = 0? thanks in advance

[strange zodiac]

on line 7 it should just be b no need for the ''

you would use '' if a is a string datatype and you are assigning it a value (string a = 'b')

[quiet vault]

So basically the LEDs wont get as much light but they wont be ruined, thats it? Also thank you!!

[idle dew]

thanks a lot, but whats the underlying reason for 98 to be printed?

[strange zodiac]

tbh i dont really know.

[idle dew]

ok, thanks for ur help anyways

[strange zodiac]

np. im pretty sure someone can answer if they know

[lucid oyster]

its the ascii code of the character b see here https://www.cs.cmu.edu/~pattis/15-1XX/common/handouts/ascii.html

since you assigned your variable to the character (not string) b before and it was still an integer you print out the value of the character b, it is 98 since it converts the character to ascii code

[idle dew]

Yeah they won't be ruined. The only thing that might take a little more stress is whatever you're using to power it. Though LED's are low voltage so it'll be fine!

[idle dew]

98 is the character 'b' in ascii

Thank u, they are conected to arduino which is connected to a computer/laptop. But would u consider it a mistake not to connect with another resistor even tho it works like this? A bit afraid the teacher will consider it a mistake

[idle dew]

I mean if its only 2 LED's it shouldn't lose any voltage. I would ask your teacher and see what they have to say about it

[quiet vault]

Alright thank you!

[idle dew]

Yeah, in the real world its common to see quite a few LED's with a single resistor. Though high performance/high voltage LED's typically have their own resistors.

[quiet vault]

Okkk thank u so muchh

[idle dew]

:)

[idle dew]

Thanks alot

[quiet vault]

Hey, so basically for this project in arduino uno i have a sensor of humidity and temperature connected to the arduino which gives me the information, i also have a fan with me and i would like to program the fan to once the temperature reaches a determined number the fan starts working, for instance if the sensor says the temperature is 21ºC the fan turns on until the temperature is below 21ºC, however i honestly dnt know how to connect the fan to arduino, idk if i even have everything i need, nor do i know how exactly i could code it, can anyone please help? i will send the code i have so far and a photo of the fan, it has 12V, thank you! (Also yes i ve tried to search it up and i will continue to but im not finding what i need).

[quiet vault]

EDIT: came to the conclusion i dnt think i have everything i need to make it work, thx anyway

[kindred trail]

any student or grad DevOps or blockchain engineers?

[tribal ore]

question about c# System.IO StreamReader

i need to get the string from a txt file, when it's in Main() it works, but when i do it in a function it just returns null, the function is correct(it works if i replace it with the same string in the program rather than making it read from the file) so idk what is messing with it, or how to fix it

[tribal ore]

wohooo i made it work by not using ReadLine() but rather ReadAllText() and then splitting it into lines

[unborn topaz]

Tech/cs/cis/mathematicians/mechatronics guys and gals can someone enlighten me which programming language used to build battlebots?

[modest abyss]

well yea but I gotta ask ppl about this to make research it has to be specific

[nova basin]

Smth no one thought abt. 🤔 it could be any field or just education?

[idle dew]

use c++

[paper crow]

I think you have all you need, just connect the negative of the fan to ground in the arduino and the positive to a DIP that you want to use, make the code to put high Voltage level and your fan will start working

If you wanted to adjust the speed that's another story because you may need to simulate a PWM, I don't know what is it supposed to do...

[quiet vault]

Ah i think i tried that i tried a lot of stuff but the thing is dnt i need something to power the fan? Cause the fan is 12V and i dnt think it was receiving enough volts from arduino

[quiet vault]

I really just wanted it to move ahah

[paper crow]

ohhh your fan is 12V

[quiet vault]

Yahh that is a issue right?

[paper crow]

does your arduino have any 12 output?

or just 5V

?

[quiet vault]

No sadly just 5v

[paper crow]

mmm

[quiet vault]

I did see it move once but barely moved cause it dsnt have enough volts

But i dnt have anything to give it volts

[paper crow]

yeah...

[quiet vault]

Well its ok i already send the report to the teacher and i wrote what i did but that i wasnt able to conclude this cause i didnt have all the materials necessary (all my material is borrowed and in college yah maybe i would have to buy it but in high school i think the teacher will understand). Thanks tho!

[paper crow]

you could have tested it with another LED though

you imagine that another led ON is the fan ON and viceversa

[quiet vault]

I do have 2 LEDs but i didnt fully understand this

[paper crow]

because you cannot make the fan work, because no 12V supply... you can pretend a LED is your fan

[quiet vault]

Ah to put the light on if the temperature reaches a determined number yah i did not think of that :'(

[paper crow]

yeah

[quiet vault]

I am currently a bit busy but i will try that later and if i can i will update the report and resend it, thank u for the idea!

[paper crow]

I used to do that back in uni when testing at home without the actuators, because those were at the lab

[quiet vault]

Yeah it was a good idea idk why i didnt think of that ahah thank you!

[paper crow]

Next time, dont worry! My pleasure

[red hare]

@quiet vault és portuguesa?

[quiet vault]

Talvez porquê? Ahah

[red hare]

O código que partilhaste tinha os comentários em português 😅

[quiet vault]

Verdade ahah

We should talk in english here tho

So whats up with 6 april? Ahah

[red hare]

Of course

😆

[quiet vault]

U are too?

[red hare]

Yes

[quiet vault]

Cooll

U worked with arduino as well?

[red hare]

Yeah, I also own a raspberry pi for personal projects

[quiet vault]

Cool, this is only for a physics project tho

[red hare]

Well, if you ever need help programming related or math, you can add me and we can talk in portuguese, I'm usually online

[quiet vault]

Sure, thx

[quiet vault]

Hey again i just did the idea u gave me and it worked just fine! Thx again!

[paper crow]

Great!!

anyone knows how to use microsoft access?

[crisp flame]

im trying to get this code to run but it keeps returning this error despite me checking the brackets several times, does anyone see any issue? this is being written in arduino in c

theres more code above that i can send if necessary but i think its a bracket problem isolated to this function

[indigo mantle]

You’re using else without if
You might want to put the two rotateRight() calls within the if scope and then else will work fine

[paper crest]

I mean, you dropped an "}" before else, the error it's understandable enough

Look the code before the else if

The last else if

At the rotateRight you should put "}"

Hello
Do you know wether there is some good App/Website/program to track studying? Where you can log that you studied 2h of fluid dynamics and 1h of spanish etc and it then lets you visualize this data? I've been only able to find programs to plan study sessions, not to track them.

[quiet vault]

Hey, i think forest premium does that, it is payed but as far as i know its not too expensive, i dnt have it but if u search it up i think u will see it works for what u want

Or maybe try to see if any of these works better for u

[red hare]

honeslty, a simple excel sheet is the best tool for this

plus you can perform computation on the data data you log, for statistic purposes or whatever

And you can format the data however you want

It's a very very powerful tool once you understand how it works

[sour terrace]

Ew

[unkempt smelt]

hiii could someone pleasee tell me what is wrong between the line number 4 and 32 ,i'm really confuse,sorry for the italian```c++

Can codechum still track activites even if the teacher is not in premium?

[red hare]

That's... The hole code

Also there is a few things wrong

Post the errors you are getting and pin me, tomorrow if no one helps you I'll reply, it's really late here currently

[idle dew]

Copy the error name and Google it you will find many solutions for different problems and don't wait for others help focus in you work and try to figure out what's wrong there sorry I'm not into c language so yup good luck Mario hahaha <33

[shrewd canopy]

i have a question with teams

what this shield in the upper left corner?

does it mean i can't use programs like obs to record my lesson?

[unkempt smelt]

i'm sorry,i didn't wanted to annoy you, i already searched on internet and changed the program before to sent it here,it's just that it still doesn't compile for a problem that i don't understand

[unkempt smelt]

@red hare

[red hare]

vt[n] gives you a float that is in position n in vt, the function is asking for a pointer to the start of a float array, just delete the [n] part

same for vp

[unkempt smelt]

it now gives me this, i already tried taking off the n,before but this happened,i serached on internet but i didn't get it.Sorry i'm not really good doing this

[red hare]

remove the []'s too when you pass the array to the function

just the name of the array

or if you insist on using []'s, do &vt[0]

[unkempt smelt]

thank you sooo much

you were really helpful

thanks for being patient with me, i really apreciate it

❤️

[tacit kite]

Prob just means data between you and members travels end-to-end encrypted

[red hare]

any time

[red hare]

It's means the data of the meeting is encrypted following Teams standard for data encryption.
By requiring all servers to use certificates and by using OAUTH, Transport Layer Security (TLS), and Secure Real-Time Transport Protocol (SRTP), all Teams data is protected on the network.

You can still use OBS to record your session, it has nothing to do with what they are saying

They are only referring to how the data is passed around

OBS looks at your computer video memory, not network traffic

I am a beginner at programming and want to start competitive. Therefore I am looking to start with C++ as it is regarded best for competitive.

[regal reef]

Does anybody know what :@: means in Haskell?

I saw it in the defn. of a datatype:
| Term↑ :@: Term↓

[regal reef]

nvm, apparently it means application in the paper I'm reading

Does anybody know if it is possible to have two datatypes reference each other in its definition in Agda? Apparently its possible in Haskell which Agda is based on. Something like:
type A :
_+_ : A -> B -> A
zero : A
type B :
_-_ : B -> A -> B
O : B

The type is nonsensical but gets the point across

[regal reef]

Lol, does anybody know if there is an equivalent to ref int in Agda or a number that stays in memory as the program is running. I would think not because Agda isn't a programming language but a proof checker, but I figured I'd ask in case somebody could confirm

[median hound]

idk if this is the right channel to ask this but:

How can I iterate backwards in an array with a for() thing?

(C++ related)

like go backwards in an array

cause that is something that will be in my exam and I honestly have no clue.

[errant bluff]

for(int i=arr.length-1;i>=0;i--)

something like that?

[median hound]

yeah I was thinkign about that

hmm I still don't knwo tried that but it is not working

:(

[errant bluff]

what are you trying to do

[median hound]

make an array,

and go backwards in it with a for thing

and then cout it

[errant bluff]

int[] arr = new int[]{1,2,3,4,5,6,7};

for(int i=arr.length-1;i>=0;i--){
  cout<< arr[i] << \n;
}

im pretty sure this is it

[median hound]

:o

lemme try

nope still doesn't work ;_;

[errant bluff]

do ` three times follow by cpp then paste ur code and end with the three ticks

or pastebin

[median hound]

well it says that it can't get the length of the array

[errant bluff]

do u have elements in the array?

[median hound]

i have it like this int arr[]{1,2,3,4,5,6,7};

and then in the for thing:

 cout << " text " << arr[i] << endl;
} ```

[errant bluff]

oh lol i think i used java syntax

try int x[] = {1,2,3};

[median hound]

still doesn't work

;_;

compiler error says: request for member 'length' in 'x', which is of non class type 'int [7]'

pain

[errant bluff]

yeah i googled u have to use sizeof

https://stackoverflow.com/questions/4108313/how-do-i-find-the-length-of-an-array

i was doing java syntax

[median hound]

hmm lemme build a working array going upwards first

i'll see what I can change then

[errant bluff]

try watching this

alright thank you!

omg I am stupid

Hello guyss i have an homework about code writing can someone help me with it 🥲

[velvet summit]

Can someone help me with this code?
I dont know why is_category_valid('bus', L) and is_category_valid('railway', L)return False
when i try is_category_valid('salary', L) is_category_valid('bonus', L), it return True

L=['expense', ['food', ['meal', 'snack', 'drink'], 'transportation', ['bus', 'railway']], 'income', ['salary', 'bonus']]

def is_category_valid(category, categories):
    if category not in categories:
        for v in categories:
            if type(v)==list:
                p=is_category_valid(category, v)
                if p == True:
                    return True
                if p != False:
                    return False
    else:
        return True

print(is_category_valid('bus', L))```

[median hound]

i found the answer to that one:

size_t size_arr = sizeof(arr) / sizeof(int);

for (size_t i = size_arr - 1; i > 0; i--) {
cout << "Array: " << arr[i] << '\n';
}

only problem left is: how do I do that when i = 0 and it should count from 7 downwards?

oh well don't care and fixed anotehr smol issue with that code lol

[idle dew]

if p== true and if p != False is same thing

hey guys, i hope i'm not bothering anyone but i'm thinking of taking a course that include a lot of game and web design

does anyone have advice on how to not fail? i'm usually afraid of coding and the like so if anyone had a similar experience to mine i could definitely use some advice

[floral anchor]

idk maybe take notes

[floral anchor]

who reacted with the laugh emoji

[alpine steeple]

Taking notes is not the most effective way to learn coding. The best way to learn coding is to keep practicing and build up what you already know.
I was in your shoes once, my advice is don’t procrastinate on your course, if you’re a beginner, it’s not an option. You would find yourself coding for 5 hours solving one easy question before you know it so always do your homework the day before. Don’t be afraid to look up answers, the internet is your guide! Copying code is not bad, however no progress comes at the cost of copying, so try to understand the code as you’re writing it, google what you don’t know and don’t copy paste everything down. I was afraid to code because I was comparing myself to other students but DON’T. We all are on a different path. What matters here is our own progress. Work on yourself.

[idle dew]

yeah i made that mistake taking notes when i should have been just trying to code something even if it took me months to build my own wealth of knowledge

[alpine steeple]

Same, all my classes are online and my c++ prof gave us pdfs each week. I took down notes but didn’t really write many codes either. The only thing I learned from that class are the terms/ function names and data structures

Hey

Please, create CRUD program in OOP (choose any comfortable for you programming language)

The topic of database: "types, markings and designations of paints and varnishes"
It should be at least 3 tables in database

Hope you can help

Thanks

[stark meadow]

Can someone help me with a python code real quick

[idle dew]

What language are you going to use

[rotund crow]

i think php

[idle dew]

Pick whatever you comfortable with

What database?

[rotund crow]

something like this

[idle dew]

Are you required to use a database though like MySQL or something?

[rotund crow]

yes

mysql

[idle dew]

Have you made your database?

Thats where you should start

[rotund crow]

yes

one moment

I also wrote some code

to select all from every table

but idk what to do next

(such as insert data, edit row, delete row)

Here i connected database:

Here I created new class, which extends connection class; and function that selects all from table "type":

Then I created view class (which i can call in future app):

[rotund crow]

can you do insert/edit/delete functions please?

just for one table

lfm_type

[idle dew]

Do you know SQL?

it will just be like function deleteType(id){ $sql = "DELETE FROM lfm_type WHERE type_id = " + id + ";"; }

for delete

it is all very similar

I don't write PHP so it may be wrong for function definition

[rotund crow]

honestly, im not very powerful in all this

Thank you)

[visual citrus]

can someone explain to me where I put the dots I mean how it works and what's the reason for it?

[alpine steeple]

True and false are Boolean statements

It’a not going to return anything if you didn’t declare a statement.

[wispy hamlet]

first_run = True means that we assign the boolean value True to a variable that we name first_run

The same goes for first_run = False -> we update the value of our previously-created variable first_run so that it now stores the boolean value False

if first_run: is just a Python syntax shortcut for if first_run == True:
They do exactly the same thing, but the first feels more natural because you could read it as "If it is the first run, do ..." (because that's what the variable first_run represents)
