Define oops and the four pillars in detail

Question

Accepted Answer

OOPs stands for Object-Oriented Programming. The four pillars are Inheritance, Encapsulation, Abstraction, and Polymorphism.

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of objects, which can contain data in the form of fields (attributes or properties) and code in the form of procedures (methods or functions).
The four pillars of OOP are Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance allows a class to inherit properties and behavior from another class.
Encapsulation is the bundling of data with the methods that operate on that data, or the restriction of direct access to some of an object's components.
Abstraction is the concept of hiding the complex implementation details and showing only the necessary features of an object.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
