C project with primes

Hi . I'm having some trouble making a C program, which entitles the user to type in an integer, and the program needs to state all the prime numbers inbetween 0 and the number , now the trick is, since we weren't taught yet strings and square roots in the class we're not allowed to use them in the program, i don't know what to use instead..anyone have an idea??

Please read the post for new users with particular regard to searching the forum (and using code tags if you post code). Prime problems are quite common questions.

Even without using square roots or primes this should still be a relatively easy project. I doubt your teacher would ask it of you without giving you the proper informaiton.

All you should need is integer input, looping, and multiplication.
