ur furst misTAKE es that u spk like a 5 yr old chld.

Your second mistake is to use a compiler from before 1998. C++ has improved a lot in the last 15 years and you're not helping yourself by using an old, incorrect compiler.

An int divided by an int will give an int. What is 4/3? 1. What is 2/3? Zero.

WHat does your code not do that you think it should, and vice-versa? You can help yourself by asking specific questions rather than just "what's wrong".
