What are fundamental pillars of OOPS programming. Explain each of them in detail.

Question

Accepted Answer

The fundamental pillars of OOPS programming are encapsulation, inheritance, and polymorphism.

Encapsulation: It is the process of hiding the internal details of an object and providing a public interface for interacting with it.
Inheritance: It allows creating new classes by inheriting properties and behaviors from existing classes, promoting code reuse.
Polymorphism: It enables objects of different classes to be treated as objects of a common superclass, providing flexibility and extensibility.

Accepted Answer

Object oriented programming is based on 4 pillars - 
1. Encapsulation - It is referred to as binding or wrapping up of data or member functions (Methods) into a single unit i.e class. 
2. Abstraction - It is process of showing only necessary information of an object/entity to outside world and hiding all other irrelevant information.
3. Inheritance - It is a process in which a child class (subclass) acquires/inherits all the methods and properties of its parent class (superclass).
4. Polymorphism - It refers to ability of a property, function or object to take up multiple forms.
