Murach's C++ 2008
How to work with inheritance

This chapter shows you how inheritance is used throughout the .NET classes and how you can use inheritance in your own C++ classes. When you're done, you'll know how to create base and subclasses, how polymorphism works, and how to use casting with inheritance.
     To make sure that you get all of that, this chapter presents a complete application that uses a Product base class, Book and Software subclasses, and a ProductList class that inherits the List<> class (one of the typed collection classes). Wow!
