Inheritance is a powerful, object-oriented language construct in which one class can be related to another class using an is-a relationship. Using inheritance, you can construct complicated class hierarchies in which one class is a parent or a base of another class. Is-a relationships are a great way of performing object-oriented design and are complemented by has-a relationships, which are implemented using composition, rather than inheritance. Explore inheritance relationships by setting up an inheritance hierarchy in C++ and specifying one class as the parent of another class. Then discover how member variables and methods are accessible from the drive class, as well as from external code. Finally, investigate base class access specifiers, and find out how they work with member access specifiers. When you're finished, you'll clearly understand how to use inheritance for is-a relationships and how to identify uses for private inheritance.

WHAT YOU WILL LEARN

  • discover the key concepts covered in this course
    recall how is-a relationships are modeled with inheritance
    contrast is-a relationships and inheritance with has-a relationships and composition
    inherit using public inheritance
    access members of base and derived classes
    compare public and private members of base classes
    use the protected access modifier for derived and external classes
  • differentiate the public, private, and protected access modifiers
    recall how private, public, and protected inheritance works
    use the base class access specifier
    use ‘protected’ as the base class access specifier
