Cameron,

I can not identify exactly where your problem is. Here are some ideas.

I would add a check after incrementing time and set time = 0 if time < 0.

I would look at where time is declared and insure that it is static. Beware of dynamic initializations...

As a matter of style, I would use the form ((A > B) && (A < C)) rather than (A > B && A < C) when working with students. It adds nothing to the speed of the code and eliminates the memorization of operator precedence.

Lastly, I would add a printf to determine what is going on. I strongly suspect the initialization of time is either implicit or the variable is getting stepped on between loops.

Regards,

Mike
