Explain what is OOP?

Object-oriented programming (OOP) is a type of computer programming, also more commonly known as software design, in which the programmers define the data type of a data structure and the types of operations or functions which can be applied to the data structure.

The data structure becomes an object that includes both data and functions. Additionally, programmers can create relationships between one object and another. Object-oriented programming basically aims to implement real-world entities in programming. These include data abstraction, data encapsulation, inheritance, polymorphism and more.
