Novice question.. please help.

Im still new into C programming, and I have a quick question:

How do you make a kind of subprogram within a program? No, not really a program but more like sequence of commands so I woudn't have to repeatedly declare it again and again?

If my question is too confusing to understand (sorry 'bout that :( ), what Im talking about is C's version of Pascal's procedure.

It's called a function in C.

Code:

---

#include <stdio.h>

void foo(void) //a function!
{
  printf("Hello");
}

int main(void)
{
  foo();
  return 0;
}
