Lesson 1

Inheritance and pure Polymorphism

This module explores the fundamentals of inheritance and pure polymorphism, including the use of derived classes and virtual functions to create a class hierarchy.
You will learn:
  1. What inheritance is and why it is so important to the object-oriented programming paradigm
  2. What virtual member functions are and how they are used
  3. How to derive a class from a base class and create a class hierarchy
  4. How public inheritance implements an ISA relationship between a derived class and the base class
  5. How a reference to the derived class may be implicitly converted to a reference to the public base class
  6. What pure virtual functions are and why they are useful in creating abstract base classes
  7. The uses of the C++-specific cast operators
  8. How to use Runtime Type Identification (RTTI) to safely determine the type pointed at by a base class pointer at runtime
  9. How to code exceptions to catch unexpected conditions
