Sorry, I didn't mean for my sloppy coding, and using mostly code I found
on the net, to start a debate. :/ 

so, the stdio.h was the problem with the rand(). That part of the code
is what I got off a tutorial, so I assumed it to be correct. as for my
code for slowing down the program, i should do something like delay(250)
or something... and for the 'void main(void) y'all confused me a bit.
should i do something like:

int main()	
{
...
return 0;
}

remember, newbie here, just trying to clear things up in my mind. I'd
like to do things correctly.... someday. please be patient.
