int main(void)
{
	srand(time(NULL));
	player1();
}

The error part, when I run this program. I get a warning saying prototype for player1 missing, I know there is something wrong with the functions. Any help please.

Thanks a lot gerard4143

Hei, that solved the problem but can you explain what you did, and I was ruining my code using tons of pointers here and there.

Its called forward declaration and its used so the compiler has an idea what player1 is.

int player1(void);

This is all the information the compiler needs to generate a function call to player1.
