Maybe, I guess, most likely, I don't do C.
It just that when the function is called within the main, the compiler need to check if the parameters match. That's way if you define the function after the main(), the prototype is required before main().

Code:

#include<stdio.h>

int mult(int x, int y){
   return x * y;
   }

  int main(void){
    int x = 3;
    int y = 2;
    int c = mult(x,y);

    printf("hello there 3 times 2 is %d, and i'm calling this function inside main without a prototype",
    c);
    getchar();
    return 0;
    }

This code works fine . I compiled it with dev c++ 4.0.
I suppose it makes sense since a #define macro can also be used as a fucntion and is defined outside of main.



Maybe when the code is longer there are potential problems. The best bet of course is to follow ANSI standards and do your prototyping.
