What are the Pillars of OOPs?
Object-oriented programming (OOP) is a programming paradigm that uses objects and classes to create models based on the real world. OOP is based on three main pillars: encapsulation, inheritance, and polymorphism. In this article, we will discuss the three pillars of OOPs and how they work together to create a powerful programming language.

Encapsulation
Encapsulation is the process of wrapping data and code together into a single unit. This allows the programmer to create objects that contain both data and code. This data and code can then be used to create a model of the real world. For example, a car object could contain data such as the car’s make, model, and color, as well as code that allows the car to move and accelerate. Encapsulation allows the programmer to create objects that are easy to use and understand.

Inheritance
Inheritance is the process of creating a new class from an existing class. This allows the programmer to reuse code and data from the existing class. For example, a programmer could create a new class called “sports car” that inherits from the “car” class. This would allow the programmer to reuse the code and data from the “car” class, such as the car’s make, model, and color, while adding new code and data specific to the “sports car” class, such as the car’s top speed.

Polymorphism
Polymorphism is the process of creating objects that can take on different forms. This allows the programmer to create objects that can be used in different ways. For example, a programmer could create a “vehicle” class that can be used to create both cars and trucks. The “vehicle” class would contain code and data that is common to both cars and trucks, such as the vehicle’s make, model, and color. The programmer could then create separate classes for cars and trucks that inherit from the “vehicle” class and add code and data specific to each type of vehicle.

Conclusion
Object-oriented programming is a powerful programming paradigm that is based on three main pillars: encapsulation, inheritance, and polymorphism. Encapsulation allows the programmer to create objects that contain both data and code. Inheritance allows the programmer to reuse code and data from existing classes. Polymorphism allows the programmer to create objects that can take on different forms. Together, these three pillars allow the programmer to create powerful and efficient programs.
