CHAPTER 14
Polymorphism
Polymorphism is such a powerful feature of object-oriented programming that you’ll use it in the majority of your C++ programs. Polymorphism requires you to use derived classes, and the content of this chapter relies heavily on the concepts related to inheritance in derived classes that I introduced in the previous chapter.
In this chapter you’ll learn:
- What polymorphism is and how you get polymorphic behavior with your classes
- What a virtual function is
- When and why you need virtual destructors
- How default parameter values for virtual functions are used
- What a pure virtual function is
- What an abstract class is
- How you ...
