If that were the case, you'd better not call printf(), for example, from
anything other than main(); it's a function.

Try this code snippet[1] on for size:

long long int factorial (long int number) {
  if (number == 2) {
    return 2;
  } else {
    return (number * factorial(number - 1));
  }
}

Not only are you calling functions from other functions, you have a
function calling itself.  You *can* write a factorial() function so that
it doesn't use recursion, but it would be more complicated and not
really as clear.
