C++ Classes

I am new to C++ and actually doing it as part of my Bsc degree, However the prescribed book 'c++ program design' is very hard to follow and frustrating. I am battleing with understanding Classes in particular declaring the class files. Although this site goes a long way to clarify the subject - my question is does anyone know of a site that may go a little deeper into the subject of classes etc?

Thanks

Ok, here's a quick lesson on classes. This is a class.

Code:

#include <iostream.h>
class iwork //start out defining a class like this iwork can be substuted with any other name
{
     public: //basically...for now...just put your functions in public, it's good practice
     //constructor
     iwork(); //don't really worry about this, just do it
     //functions going to be used in the class
     void test1(); //gathers the number
     void test2(); //outputs the contents of number gathered in test1();
     private:
     //variables going to be used ONLY in this class...this is important when you get into inheritance.
     int number;
};//<-------note the semicolon
iwork::iwork()
{
     //just makes the constructor happy
}
void iwork::test1()
{
     cout<<"Enter a number." <<endl;
     cin>>number;
     test2();
}
void iwork::test2()
{
     cout<<"The number entered is:  " <<number <<endl;
}
main()
{
     iwork inst; //creates an instance of the class so you can use it.
     inst.test1();
     return 0;
}

Please ask me any questions you may have...I'm still a newbie myself, but yea...I wanna help =) My AIM name is RevolutionST.
