 * Inheritance
 * ===========
 *      - Class is used to describe properties and behavior of an object.
 *      - It is a process of inheriting properties and behavior of existing class into a new class.
 *      - Existing Class is called as Parint Class, Old Class, Super Class, Main Class and Base Class.
 *      - New Class is called as Child Class, Derived Class, Sub Class.
 *          syntax:-
 *          ======
 *                  Class Parant_Class
 *                  {
 *                  
 *                  };
 *                  Class Child_Class:Visiblity_Class
 *                  {
 *                  };
 *       - Inheritance is the process by which new classes called derived classes are created from existing classes called base classes.
 *       - The derived classes have all the features of the base classes.
 *       - The programmer can chose to add new features specific to the newly created derived class.
 *       - Inheritance provides the idea of reusability i.e., code one written can be used again and again in number of classes.
 *       - The above concept of reusability achieved by inheritance save the programmer's time and effort.Since the main code written can be reused in various situation as needed.
 *       - Any change made to the base class code automatically get propagated to the inherited code. This will provides that it is possible to change one of code and all current object will automatically be updated.
 * 
 * Q. What are different types of inheritance?
 * Ans:- types of inheritance are :->
 *          - Single Inheritance
 *          - Multiple Inheritance
 *          - Multilevel Inheritance
 *          - Hierarchical Inheritance
 *          - Hybrid Inheritance
 *      types of Inheritance in terms of Visiblity:->
 *          - Private
 *          - Public
 *          - Protacted
 * 
 * Single Inheritance
