INHERITNCE

Inheritance is a fundamental principle of object-oriented programming. It allows a class to "inherit" (behavior or characteristics) of another, more general class. For example, a lion belongs to the biological family of cats (Felidae). All cats that have four paws, are predators and hunt their prey. This functionality can be coded once in the Felidae class and all its predators can reuse it – Tiger, Puma, Bobcat, etc. Inheritance is described as is-kind-of relationship, e.g. Tiger is kind ofAnimal.

Introduction to Object-Oriented Programming 

Object Oriented Programming will be mainly divided on 4 principles.These are like heart of OOP.

• Inheritance

• Abstract

• Polymorphism

• Encapsulation      

Here there are the main principles of Object oriented programming.We will these main principles one by one with next our posts.Object-oriented programming is the successor of procedural (structural) programming. Procedural programming describes programs as groups of reusable code units (procedures) which define input and output parameters. Procedural programs consist of procedures, which invoke each other.
