Designing Reusable Code   «Prev  Next»
Lesson 1

Introduction to writing Reusable Code in C++

This course teaches you the basics of polymorphism and inheritance, focusing on function and operator overloading and on creating class hierarchies. Throughout the course, you will gain skills that help you build adaptable, reusable, object-oriented C++ code.
After completing this course, you will be able to write C++ programs that:

C++ Polymorphism

Polymorphism is such a powerful feature of object-oriented programming that you will use it in the majority of your C++ programs. Polymorphism requires you to use derived classes, and the content of this module relies heavily on the concepts related to inheritance in derived classes.
In this module you will learn:
What polymorphism is and how you get polymorphic behavior with your classes
  1. What a virtual function is
  2. When and why you need virtual destructors
  3. How default parameter values for virtual functions are used
  4. What a pure virtual function is
  5. What an abstract class is
  6. How you cast between class types in a hierarchy
  7. How you determine the type of an object passed to a function as the argument for a parameter that is a reference to a base class
  8. What pointers to members are, and how you use them


Course Goals
  1. Use special conversion member functions to convert from a user-defined type to a built-in type
  2. Overload operators and member functions to give them additional meanings
  3. Use derived classes, virtual functions, and abstract base classes to create class hierarchies
