classes and int main()

I am looking for some good tutuorials and information sites on c++ classes and how to structure and write them. I have a very large int main() that i would like to try and separate into classes so int main() is as small as possible. Does anybody have any suggestions for good resources? I can also post my code if its helpful.

Every class should represent a type of object conceptually. The object could represent data, or it could manipulate other objects, or both.

Everything else follows from that basic idea.
