stuff on functions

/* So  here's the skinny on void & returns:

All functions, like double or int, should return _something_. That's why you use the return line. 

The only time a function DOESN"T return a value, is when you use void. Void means the function does something, but doesn't return a value.

So for example you could have two functions: */


// simple main function. just uses two other functions to do everything
int main() {
  // call the print function and pass it the add function as a parameter
  print(add(2, 4));

system pause;
return 0;
}

// simple function to add values. MUST have a return
double add(int a, int b) {
  return (a + b)
}

// a void function doesn't need to return anything, it JUST prints.
void print(int sum) {
  cout sum;
}
