Programming Languages

Object-Oriented Programming has the following reasons to be used:
1) OOP provides a clear modular structure for programs.
2) OOP makes it easy to maintain and modify existing code.
3) OOP provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer.
4) Code reusability.
5) It is suitable for real word problems and real world works.
Few more points for better understanding are:
Why? Because if you stick to the rules, it makes complex code easier to develop, reliable, maintainable, and generally better.
OOP insists that you think about what you expose to the outside world, it lets you change the implementation of an object without affecting any other code. (Encapsulation)
It allows you to have many different functions, all with the same name, all doing the same job, but on different data. (Polymorphism)
It lets you write a set of functions then expand them in the different directions without changing or copying them in any way. (Inheritance).
