Question

What is Encapsulation? Why do we do it?

Answer 1

Encapsulation is the wrapping together of data and function. I know this only.

Answer 2

Answer:

The system of wrapping data and functions into a single unit is known as encapsulation.

Data encapsulation is the most important feature of a class. The functions used in a class can only access the data items. These functions provide an interface between data items of the objects and the calling program. This is the reason of using encapsulation.
