Object oriented programming is a programming paradigm that was developed to overcome the drawbacks and limitations of particularly procedure oriented programming. The major need for developing such languages was to manage the ever-increasing size and complexity of programs.

Inheritance:

Inheritance is the process by which objects of one class acquire the properties of objects of another class. It supports the concept of hierarchical classification. 

Polymorphism:

Polymorphism refers to the way of operating the same operator in different ways and different method or purpose. Operator overloading and the operation overloading are the examples of polymorphism. For example ‘+’ operator can be used for arithmetic operation and string concatenation both.

Objects:

An object is any entity, thing or organization that exits in real world. t consists of two fundamentals characteristics: its attributes and behaviors. For example: a dog is an object having attributes such as color, weight, age, etc. and behaviors such as barking, wagging tail, etc. 

Class:

A class is the collection of similar objects. It is defined as the template or prototype to define the common attributes and behavior for all the objects of the class.
