Quite a few of your explanations contain subtle mistakes. An include mechanism if there are external libraries are needed, like here the puts function While include is often used to pull in declarations from libraries, it' not really required, nor is that the only function. But I get why you'd want so simplify this for beginners.. An main function as entry point older C compiler where OK with return type ‘void’ Strictly speaking int main (void) and int main (int argc, char *argv[]) are the only signatures, and only in a hosted environment. Since C99 implementation-defined signatures are allowed. A simple function like puts that does something, puts is defined in the included library It's declared in the header. The function definition is somewhre else. A return function that satisfies the function type for main also older C compilers did not need that Return is not a function, and for main it's optional since C99. More on reddit.com

The void part isn't needed. Try this:
#include <stdio.h>
int main()
{
printf("Hello World");
return 0;
}
or try this:
#include <stdio.h>
void PRINT() {
printf("Hello World");
}
int main() {
PRINT();
}
Make sure to #include <stdio.h> at the top.

Hello world!
So I'm new to programming and I was trying to write a function "loop1" that adds 1 untill it got to 20 and for every result it would print it to the screen.Then I called the function loop1 before the main() And in the main() function I called a printf that outputs the results from loop1.
This all works but... when I add another function loop2 that adds 2 untill it gets to 20 and call it in the same way only the 1st loop gets printed out to the screen.
#include <stdio.h>
int loop1();
int loop2();
int main()
{
printf(loop1());
printf(loop2());
return 0;
}
int loop1()
{
int incr = 0;
while( incr <= 20)
{
printf("%i\n", incr);
incr++;
}
}
int loop2()
{
for( int incr = 0; incr <= 20; incr = incr + 2)
{
printf("%i\n", incr);
}
}This what I wrote but only the results of loop1 are getting printed to the screen.What am I doing wrong?
Ps: If you are wondering why I'm using 2 different methods to add it's because I'm new to programming and am still learning.

The 2 functions does not return any value so you don't have to print anything just call them in main.

case is important in C and standard library functions and keywords are all lowercase. So Int should be int, Printf should be printf, For should be for. Now you can name your own functions and variables with whatever case you want as long as you use them exactly as you declare and define them.
