In this we will learn about Encapsulation in C++

 

Encapsulation in C++

Encapsulation is a method that is used in object oriented programming . Encapsulation is

 defined as wrapping of data and function in single unit is known as encapsulation .

For real based example

 

   Consider a real life example of encapsulation in C++ , in a company there are different

 type of section like sales section , account section and manufacture section similarly the

 sales section handle all the sales related activities and hold all the record . account section

 handle the accounts of the company and manufacture handle when product is is

 manufactured . Now there may arise a situation when for some reason and official from

 manufacture section needs all the data about sales section in a particular month . In this

 case , he is not allowed to direct access the data of sales section . He will have to contact

 first for the some official officers from the sales section and request him to give the

 particular data  . Encapsulation is used in this process .

Encapsulation is also used for data hiding . In this above example data of any section like ,

 sales , account , manufacture hidden form any other section .

Example of Encapsulation

#include<iostream>

Using namespace std ;

Class encapsulation{

    Private :

// data hidden from outside the world !

     Int x ; 

Public :

Void set( int x  ){

x = a ;

}

Int get ()

{

Return x ;

}

}; 

Int main( ){

// Object Created 

Encapsulation obj ;

Obj.set(5);

Cout <<obj.get();

Return 0 ;

}

Output

5
