what is oop?

Object oriented programming refers to a type of computer programming, which was

invented to overcome the drawbacks of the POP. It follows “bottom-up” programming

approach.

OOP gives more importance to data and does not allow it to flow freely around the

system. It ties data to the functions that operates on it in the form of Class.

In POP approach, the problem is viewed as a sequence of things to be done, such as,

input taking, calculating and displaying. The primary focus stays on functions which will

be used to accomplish each task.
