What is the necessity & advantages of Oops?

Object-oriented programming is often the most natural and pragmatic approach, once you get the hang of it. OOP languages allows you to break down your software into bite-sized problems that you then can solve — one object at a time. This isn’t to say that OOP is the One True Way.

What is the necessity and advantages of Oops?

OOP provides a clear modular structure for programs which makes it good for defining abstract datatypes where implementation details are hidden and the unit has a clearly defined interface. OOP makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones.
