#include <stdio.h>
int main(){
printf("Hello, World!");
return 0;
}
#need help figuring out the first c problem itself

Did you watch that video?
frozen wolf
i did
apparently i should not delete the given code and only make a single change
which i do not at all know
eh
so i just had to change bye to hello and mars to world
but now i have no idea how the function works
mighty verge
Which part of the function do you not understand?
If you copy/paste your code here, and spell out your confusion, someone may be able to explain things to you
frozen wolf
well the code in itself is something i don't get, in the end i did this:
#include "hello_world.h"
const char *hello(void)
{
return "Hello, World!";
}
as to the change a single string reference but how the code works is a different thing and the part i don't get

Increase your chance of getting help and look like a pro by sharing codeblocks not images. For example, you can type the following. Note, the ``` must be on their own line.
```
for number in range(10):
total += number;
```
Discord will render that as so:
for number in range(10):
total += number;

Do you understand any of the lines? Most of the lines? None of the lines?

im back i was awk for a while
//why are we accessing that?
const char *hello(void) // const char cause we are returning a constant character? but no idea about the next part
return part makes sense```👋🏼 Hello!

Header files are used to share what functions exist with other code files. It's part of how C code is compiled; each file is compiled itself but needs to know what other files contain. Header files are used to share this info.

const char * is a "string" in C. void means this function takes no arguments.
Did I miss any part?
frozen wolf
i get the void part so is hello the function name and since by default strings don't exist in c
we use the *
as a pointer to move to each character
mighty verge
* says we are dealing with a pointer to chars, which is how strings work in C, yes
frozen wolf
okay i see
what about when we include stdio.h is that sort of inbuilt header thats there
mighty verge
stdio is part of the ... standard library that does IO stuff. Most languages come with a library of helpful functions you might want to use.
