[celest sage]

you can use some macros to reduce some characters

if that's allowed

[loud stream]

Loop.

[dapper spoke]

What is the assignment exactly?

[dapper spoke]

not very specific

can you send the instructions verbatim

[regal granite]

you have a lot of repetition insert/begin/replace/find, you could save characters by putting all your arguments in arrays and then looping through them

you could also precompute all the z[0].find("#"), they will be fixed

and if you don't need both <array> and <vector>, you can drop one include

[dapper spoke]

Can you send the .txt file?

of the provided file

lol, no you don't

hmm, strange

[broken beacon]

I think you could have all the "turtle doves", "french hens", etc stored in a vector, then loop in reverse and add the number in the loop

If you have fmt you could do "On the {} day of christmas my true love..."

Nested for loops should make it pretty easy

[marsh fog]

im trying to do a array loop but idk how i could call lines that come after others in the array part before others

cuz in my for loop, im thinking of incrementing a variable and outputting thhat many strings of the array

but array gets output from a b c for eg

i want c b a

but i want to add a string in place D next

not A

[broken beacon]

for (int i = 1; i < 13; i++) // day count
{
for (int j = i-1; j >= 0; j--)
{
printindex(j);
}
}

Smth like this? Idk

[marsh fog]

hmm

yeah

[broken beacon]

Iterate through the thing in reverse

Also since it's all fixed anyway, might as well hardcode them

[marsh fog]

from 12 down to 0?

if so, i tried it

i dont understand that

[broken beacon]

For the array printing?

[marsh fog]

yeah

[broken beacon]

What did you not understand

[marsh fog]

try adding what i told u originally, adding loops, how do i ncrement the day @ {} ?

[broken beacon]

With a loop

[marsh fog]

like how do i correct this {cout << x,num[0];

[broken beacon]

?

[marsh fog]

sorry im maiing youu so confused

making*

also yeah the code i sent has some errrors to fix but i want to fix this frist since you are here rn

[dapper spoke]

i would use 2 string variables

[broken beacon]

std::format(x, num[i])

Or fmt::format

[marsh fog]

cout << std::format(x, num[i]); ?

[broken beacon]

Yes. Include <format> and use c++20

[dapper spoke]

replace x with the text

[dapper spoke]

lmao

[broken beacon]

Oh yeah, might as well just use the literal since you're using it once

[marsh fog]

ohh so i get rid of "string x=..." line

[broken beacon]

Me omw to delay c++29 to 2030

[dapper spoke]

Based as can be

[dapper spoke]

format is c++20 i believe

[marsh fog]

wow so my prof scuffed me?

[dapper spoke]

like what he said

[marsh fog]

prof wants us to use this specifically

im sad

[broken beacon]

Oh then just use fmt::format

[dapper spoke]

umm did you run it with the flag -std=c++20

[broken beacon]

Include the fmt header instead of <format>

[dapper spoke]

tbh your prof won't run it with the argument so probably shouldn't use it

[broken beacon]

fmt::print(blah, blah2) is shorter than std::cout<<std::format(blah,blah2) as well

[marsh fog]

#include <format.h>?

[marsh fog]

prob shouldnt use..?

what?

[broken beacon]

In your origibal post you have <fmt/format.h>

[dapper spoke]

don worr ab it

[dapper spoke]

true !

[marsh fog]

i did but then im re writng everything

and even got rid of all the includes accidentally

so i was confussed

but i added it back

[broken beacon]

I mean, that's the header you should be using

[marsh fog]

and still erorr

[broken beacon]

Can you send the line where you used the fmt

[marsh fog]

    cout << fmt::format("\n\nOn the {} day of Christmas \nmy true love sent to me:", num[i]);

[broken beacon]

It looks like youre missing the fmt.c or whatever that's called

It should be compiled and linked

[marsh fog]

oh god

what is that now....

wait

one sec

nvm

i thought since im writing this code in a standard file, one that i created for myself, that if i copy paste the code into the file the prof provided, that perhaps it would run in his provided "template" cuz he may have added stuff from the libraries that we may have needed

[broken beacon]

It's a compiling thing

[marsh fog]

so compiler is dumb?

[broken beacon]

No

You have to add the fmt file to the compler flags

format.cc

[marsh fog]

This?

From this yt https://youtu.be/tUZAnPT5Zvc?si=VsGvXa7h7TYx_gbY

[broken beacon]

Uhhh i wouldnt trust that

https://github.com/fmtlib/fmt

Grab it here ^^

[marsh fog]

Damn Alr

[marsh fog]

so i have to take the zip i found from ur link thing and somehow insert into the compilers files?

[dapper spoke]

Do the directions let you use 3rd party libraries?

:0

[marsh fog]

haha... idk

tbh he himself said:

[marsh fog]

oh

didnt read that

well more like

didnt know fmt was a didfferent library

[dapper spoke]

ive never used it

[marsh fog]

i see

now im lost on what to do yay

si there a slower way to do what we wanted to do?

[dapper spoke]

ya

[marsh fog]

hit me

i dont care anymore i give up

i'll just take the B

[dapper spoke]

str1 = "\n\nOn the ", str2 = " day of Christmas \nmy true love sent to me:";

in between put in a variable

for the num

num[i] yeah

probably simpliest way

[marsh fog]

k lemme try

my compiler is dying

heh

[dapper spoke]

wdym

[marsh fog]

well its lagging

but i think igot it tho

[dapper spoke]

nice

[marsh fog]

cant type in the code cuz its freezin up but yeah

um not at all

idk why its doing that

[dapper spoke]

it shouldn't lag lmao

[marsh fog]

ig this thing is built diff

it usually doesnt lag lol

the coding thing

pc never

[dapper spoke]

werid

[marsh fog]

oh btw, this is as small as it can get right?

i cant shorten ?

hmm.. when i try running this, it really struggles

[dapper spoke]

Yeah because you're accessing stuff outside the array

in the for loop

[severe sinew]

Undefined Behavior

Undefined behavior occurs when you violate rules specified by the language. For example: Reading uninitialized memory, performing out-of-bounds memory access, signed integer overflow, and race conditions.

Example: Read Indeterminate Val.

int i; // default init,
       // indeterminate value
while(i < 10) {
    printf("%d\n", i++);
}

Example: Out-of-Bounds Access

int arr[10];
for(int i = 0; i < 20; i++) {
    arr[i] = i; // [i] out of
                // bounds
}

Consequences of UB

Compilers are not required to provide warnings or errors about UB. Often it is undetectable at compile-time. Performing actions which are UB can render your entire program's behavior undefined, leading to anything from crashing to summoning Eldritch Abominations.

• What is Undefined Behavior?

Sanitizers can help identify UB. For more info, look into address sanitizer (ASan) and undefined behavior sanitizer (UBSan). See !howto asan

[marsh fog]

hm thats a problem?

[dapper spoke]

Yeah? of course

How is it not a problem

[marsh fog]

it doesnt feel like it to me...

so i just move everything into the for looop..?

except the array itself

[dapper spoke]

What?

why would you do that

[marsh fog]

^

[dapper spoke]

Look at the first for loop

also you understand that arrays start at 0 right

[marsh fog]

staring into its soul rn

[marsh fog]

yes...

[dapper spoke]

so num[12] is UB

the for loop exits at 13

[marsh fog]

i fixed it just as u said 12

heheh

me samrt

smart

( i wish)

[dapper spoke]

now fix the other for loop

wait it might be correct

[marsh fog]

wait hold up

im missing one day

[dapper spoke]

Yeah, remove the -1

[marsh fog]

yay

it worked

[dapper spoke]

it's not 100% correct, make sure to compare the texts

[marsh fog]

hmm why was that there in the first place?

[dapper spoke]

dunno, u wrote it

[marsh fog]

yeah i know i saw

first day caant have "and a" in its output

[dapper spoke]

yeah, remove the and

[marsh fog]

ig its on me for not noticing

[dapper spoke]

true

[cloud cliff]

this is so embarassing man

@marsh fog just plain embarasing dawg

[marsh fog]

bruh what

[cloud cliff]

deleting your message too

[marsh fog]

fyi i didnt even use their codes

im deleting cuz idk if u copy

on my life

[cloud cliff]

LMAOOO

[marsh fog]

?

bruh what

@cloud cliff whyd u go quiet

i dont understand what makes u think this is embarassijg

[cloud cliff]

: )

[marsh fog]

@cloud cliff bro npc

its more embarassing seeing someone who clowns on another for no reason

the fact that u are also here in this server doesnt make u less embarassing than me @cloud cliff

i came for guidance... you for clowning?

tf?

the audicaty man

no responses?

@cloud cliff

stop hiding dawg

[cloud cliff]

u done talkin dawg?

[marsh fog]

finally replying

and you dipped again

[marsh fog]

your arguments are so strong wow

[dapper spoke]

Scroll up if you think he copied me? There's clearly a lot of discussion going on.

As well as the for loops are not similar to mine 8)
