VSCode and C

[visual pumice]

You need to install a compiler bro

https://code.visualstudio.com/docs/cpp/config-mingw

[oak gazelle]

@rich hornet has reached level 4. GG!

[visual pumice]

Ok

Did you install c/cpp extension

Ok when you click the green button its going to tell you to choose compiler

As far as i know gcc is for C

And g++ is for C++

Play button on the top right

Try switching to another file and going back to the source file it gets hidden sometimes

Or you messed something up while trying to setup C on VSC 💀

Oh you dont know how to use vsc 😭

Well there should be a green ▶️ button

That compiles and runs the code

[visual pumice]

.

Bro send ss 💀

Bruh i dont remember such a thing

@visual pumice has reached level 49. GG!

[visual pumice]

50 BEFORE GETTING BANNED 🔥🔥

[zinc rose]

show a screenshot of your full window please

your running button is on the top right, it's just not green 🙂

left to the settings icon

select the first one

[young patio]

here's a thought: compile via command line 👍

[zinc rose]

is gcc in path?

cmd -> gcc --version

then click on open launch.json

but it opened a json 👀

good

what?

lol

find the json in your directory

[zinc rose]

in your .vscode folder

[visual pumice]

I forgor

[oblique ingot]

erm

dont use vscode

simple

[hot vault]

you can just open a console and compile by cc

or clang

[oblique ingot]

or just dont use vscode

install mingw

and shit

[hot vault]

at this point just use vim/nvim/emacs

[zinc rose]

did you open a file or folder in vscode?

[oblique ingot]

cmake sucks

[zinc rose]

because you can't handle it? 🤔

classic case of skill issue

[past perch]

😂

[worthy timber]

ming's is gaA use WSL, already built into windows

[oak gazelle]

@worthy timber has reached level 4. GG!

[hushed goblet]

Meson is better tbh

[oblique ingot]

cmake is baddddd

[spiral isle]

@oblique ingot How does your contribution to this chat help getting the issue solved? It's annoying for the questioner if the topic of the help-post gets changed...

[zinc rose]

can you send me a screenshot of your projects folder please?

[visual pumice]

why is there a random void parameter

[young patio]

that's usually good practice in C meaning the function doesn't accept any parameters, because int foo(); would mean accept any number of parameters of any type, although this is removed in C23 i believe

[visual pumice]

strange

because VOID can also be used to express any datatype

i might however be wrong

personally i use only c++

i also dont think you can pass random arguments unless you do args[] i thought?

which would mean any arguement

@young patio

like
int main(args[])

[young patio]

that's a void pointer

[visual pumice]

shoot bro

ive been

working with windows api

for

8 hours straight

my bad lolz

i think im going insane hah

[young patio]

void is what's known as the type-0 because it there's no value of that type

unlike say a bool which has two possible values

[visual pumice]

yeah, 1 or 0

[young patio]

there's a difference between program arguments and function arguments

here's an example:

#include <stdio.h>

int foo();

int main(void){
    printf("%d\n", foo(2, 3, 4));
    return 0;
}

int foo(int a, int b){
    return a + b;
}

this compiles in c just fine

[young patio]

;compile

[mellow pagoda]

Program Output

quimpossible | 75ms | c | x86-64 gcc 13.2 | godbolt.org

[visual pumice]

: (

use struct

pls

🙏

[young patio]

wym struct?

[visual pumice]

typedef struct to store a and b

[young patio]

;compile cpp

[visual pumice]

typedef struct(
  int a;
  int b;
) numberos;

[mellow pagoda]

quimpossible | c++ | x86-64 gcc 13.2 | godbolt.org

[young patio]

that doesn't really make sense for this particular case

[visual pumice]

yeah but its always good practise

when it comes to larger programs

[young patio]

i mean, it depends

if there's a good reason to pack everything into a struct, then yeah

[visual pumice]

well, i only use it because i work with low level windows internals

i personally

like

neat code

[young patio]

like for example a cartesian point would make sense

[visual pumice]

anything where you need to store a ton of data types

[young patio]

but like a function that computes the greater of two integers not so much

[oblique ingot]

cant you just do that in int main????

[young patio]

the hell do you mean?

[oblique ingot]

drugs

[visual pumice]

read. it was about argument passing.

you don’t pass an arguement to yourself lol

[dreamy falcon]

Does declaring a function with no args let you make multiple definitions with different args after? I didn’t know you could do what you wrote here before.

I knew that not listing parameters was declaring that any params could be passed, but I didn’t know the definition didn’t have to exactly match.

[young patio]

no, you generally can't have multiple definitions of the same symbol in C

the difference is actually clearer when you understand the different between parameter type lists and identifier lists:

// using parameter type lists

// a declaration
int max(int a, int b);

// a definition
int max(int a, int b){
  //...
}


// using identifier lists

// a declaration
int max2(); 

// a definition
int max2(a, b) int a; int b; {
  //...
}

using identifier lists, the declaration can't specify it's parameters, meaning such declaration only says that max2 returns an int but may take in any number of arguments of any type, they're just not known

keep in mind that max2 can therefore be called using any number of arguments but it's undefined behavior to do so

@rich hornet has reached level 5. GG!

[zinc rose]

there is the .vscode folder i was talking about

[visual pumice]

@rich hornet i strongly reccomend just using visual studio

visual studio is better anyway

i reccomend swapping

visual studio also allows you to easily install development kits, far better than VSC

[zinc rose]

it's different, but way easier to get started with

[visual pumice]

it’s just

a better IDE in general

i only use VSC for high level programming

[zinc rose]

vscode is no ide

[visual pumice]

well

in context, it’s being used as one

so

vs is better

it takes up more space but it also has literally everything you could possibly need

[zinc rose]

i wouldn't say it this way, but i know what you want to say

[brazen ocean]

There's an interesting debate on whether we should treat the void type as containing zero values or one single value (similar to an empty struct): https://en.wikipedia.org/wiki/Void_type

[young patio]

I'm inclined to say it is a zero-type because you can't instante it

void foo {}: // not possible

the wikipedia page mentions the () unit type in haskell as similar but in fact that type has one possible value:

void :: ()
void = ()

[hushed goblet]

Afaik haskell functions should always return variable

[young patio]

i tested this in ghci and it works

() is a value of type ()

wonky, I know

[visual pumice]

use visual studio

[zinc rose]

what's the exact reason again why you are not using visual studio?

when you try to run in vscode without a conf then it creates one

and you can modify it to compile and run your code

[zinc rose]

but visual studio is easier to get started as a beginner so good for you when you are lazy 🤔

you can make it execute a bash command as soon as you click on the start icon

same as when you would compile and start with your terminal

[hushed goblet]

For me it interface is too much overcomplicated

[zinc rose]

of visual studio? hmm i understand that

but you can just use what you need

i don't like visual studio that much myself to be honest

yes, you have to set this up in your configuration file

@rich hornet take a look at https://code.visualstudio.com/docs/languages/cpp

@rich hornet çözdünmü sorunu

[dreamy falcon]

That's interesting. I didn't know about the identifier list syntax before. I can see why you can't use identifier list syntax in a declaration as well.

Is it the case that identifier list syntax was "the original" syntax, and that parameter type lists came afterwards? I might google that later, but I'm curious about why both are possible in the language.

[young patio]

@visual pumice take a look this

[young patio]

yeah

originally the creators of C thought it was too much of a hassle having to specify the type in paremeter lists

so this exists purely for backwards compatability

[hot vault]

rel

[brazen ocean]

Thanks for explaining, I used to do it in code golf challenges before (without specifying the type), but I didn't understand the full extent of this syntax.

[young patio]

yeah, it's a bit of historical baggage that was kept in the language for more time than it should

[brazen ocean]

I've learned C++ first, all I know about C is from experimenting and looking at golf programs from others 😄

But I can still write a 5 characters valid program in C, which compiles, runs and generates a segfault 😄

[young patio]

5? including int main()?

[brazen ocean]

5 characters in total, including everything

[young patio]

care to show? lol
