There is only one thing I need help with. It is supposed to print a given amount of primes, not until it gets to the given number. IE. Say the user puts in 100, right now it will stop at like 97 or something, but its supposed to print 100 of them. Im not to good at programming, and am just trying to get by in the class. Im about to give up. I dont know why I am having sutch a hard time.
