The OOP or Object Oriented Programming is one of the most popular  programming paradigms which helps you to organize code in re the l world system. It's a tool which helps you to write complex software by thinking in terms of objects. Unlike its predecessor procedural programming paradigm which is implemented most notably by C, which solves the problem and complete task by writing code for computers, OOP style of programming allows you to think in terms of real world objects which has both state and behavior. You can view anything as objects and then find their state and behaviors, this will help you to simulate that object in code.
