What is Object Oriented Programming?

Object-oriented programming (OOP) is a programming paradigm that is based on the concept of "objects," which are instances of a class.

The main idea behind OOP is to model real-world objects and their interactions, making it well-suited for creating complex and large-scale software systems.
