Error C2143

Donny (8)
This is frustrating the hell out me.

I'm also not sure if my random number function is correct, I want a number which is either 0 or 1 at random. Obviously if D0=1 the printf statement appears. It's all related to bitwise operators.

I know there's some stuff thats declared in integers thats not used, thats for later on.

Any help would be nice, thanks!

What specifically is your first error (Error C2143)?

void main()
to

int main(){
    return 0;
}


You don't use any bitwise operators.

You only need to seed the SRNG one time: srand(time(NULL));
after that you get a random int with rand()
