Chapter 9, Problem 4RE

Program Plan Intro

Inheritance:

• Inheritance is the concept of inheriting the members and properties of a base class from the derived class.
  • The main advantages of inheritance are,
    • Code reusability and fast implementation.
    • Reduces the size of the program code.
  • There are five types of inheritance:
    • Single inheritance
    • Multiple inheritance
    • Hierarchical inheritance
    • Multilevel inheritance
    • Hybrid inheritance
  • If a subclass inherits a base class, then the member functions and data members of the super class can be accessed by the derived class.
    • But the derived class does not inherit the constructors from the base classes; each derived class should contain individual constructors.

Method Overriding:

• Overriding is a feature that allows a child class or subclass to specifically implement a method that already provided by one of its parent classes or super classes.
• If the method of the subclass has name, parameters and return type as same as the method in the super class, then the method in the subclass is said to override the method in the super-class.
