Paul has described below one way to compile your program and run it.

The reference to "return 0;" means that a correct C program would include 
that as the last line of main():

int main(void)
{
    printf("%d\n",add(3,5));
    return 0;
}

Leaving it out probably won't prevent your program from running, but it 
may not correctly indicate its success to the operating system.
