Part . Inheritance and Polymorphism

What's object orientation without a little inheritance and polymorphism?

Although it's often overused, inheritance is still an important tool—and that includes multiple inheritance. Multiple inheritance comes into its own especially when you're living in the real world and often find yourself in the situation of trying to combine libraries from different vendors. This section shows how to avoid the Siamese Twin problem when combining inheritance-based libraries from different vendors. It also demonstrates the many legitimate (and some illegitimate) uses of pure virtual functions, how to code alternatives to multiple inheritance, and how to control who gets to make use of your inheritance relationships.
