C++ Programming - OOPS Concepts - Discussion

Data hiding means " Hiding the our internal data"..
Data Abstraction means " Hiding the internal implementation".
Encapsulation = Data Hiding + data abstraction.
Encapsulation means " Binding the our internal data and the behavior" .

Encapsulation is the right answer.

Encapsulation and abstraction are both OOP principles used interchangeably to achieve better security and a high level of implementation by hiding sensitive and unnecessary data and only exposing necessary data.

Abstraction which denotes/shows the essential characteristics of an object which distinguish it from all other kinds of objects.

Ex. Consider a person details.

Doctor needs || Interviewer needs
>name of patient || >name of candidate
>age of patient || >Qualification of candidate
>height || >Result
>Blood pressure || >Skills etc.
>weight
etc.


Both of above doctor and interviewer needs the information of person but with different aspect.

I strongly suggest abstraction which involves keeping the main work and showing the interface alone.

From my thinking abstraction is right answer because abstraction show only show essential information.

Abstraction is process of identifying key aspects of an entity and ignoring the rest. So answer should be abstraction.

Data hiding means giving/revoking access members. Like access specifiers.

Eg: Public/private/protected. :).

Correct answer is abstraction not data hiding.

God knows how ATM counts cash. It is example of?

A) Encapsulation.

B) Abstraction.

C) Data hiding.

D) Data binding.
