C++ Programming - OOPS Concepts - Discussion

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.

Data hiding is also called encapsulation is correct/not?

Data hiding is the intense version of encapsulation.

According to me abstraction is the correct answer because"data hiding" refers to only hiding of data but doesn't say anything about displaying only necessary info.

Abstraction means exposing only the necessary data hiding the background information.

No @Chaitanya saying that would be incorrect.

Encapsulation refers to binding data and functions working on it in a single component But data hiding is different from it.

Abstraction - Showing essential features without including background details.

Data hiding - Controlling the accessibility of data like using access specifiers.

So the answer should be ABSTRACTION not data hiding.

If you consider the broad meaning, data hiding may seem right. But to be very precise, DATA ABSTRACTION should be the correct answer.

It hides the data and expose only some information which is declared in the person class but we can access it by public variable.

The answer is abstraction as it hides the complexities from the user and shows only the essential features. Whereas data hiding is hiding the data altogether from the user.

The answer is abstraction as it hides the complexities from the user and shows only the essential features. Whereas data hiding is hiding the data altogether from the user means data hiding means public, protective or private. Hence data hiding is correct answer.
