Object Oriented Programming (OOP) is based on the concept of objects rather than actions, and data rather than logic. One of the advantages of using Object Oriented Programming is for code reuse, which can be achieved by two ways; either inheritance or composition. It simplifies the process of seeing things in their entirety. With this type of programming, a program comprises objects that can interact with the user, other objects, or other programs. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance.

It enables a class to acquire or get the properties from another class, It makes easier to add new features or methods to a class, It provides an overriding feature which allows a child class to have a specific implementation of a method defined in the parent class, A class that is inherited by other classes is termed as super class or parent class or base class, whereas a class that extends another class is termed as sub-class or child class, Inheritance can be classified into majorly 5 types : Single Inheritance, Multilevel inheritance, Hierarchical Inheritance, Multiple Inheritance and Hybrid Inheritance. 10. This promise is predicated on the assertion that if you build generic objects they can be used and reused. This mechanism actually inherits the fields and methods of the superclass.

Object-oriented programming (OOP) is known as the most common programming paradigm. Constructors may be overloaded, which means that multiple argument lists can be used with the same name. Objects have their own properties and behavior. Abstraction is selecting data from a larger pool to show only relevant details of the object to the user.
