Encapsulation In C++

Encapsulation is a process of combining data members and functions in a single unit called class. This is to prevent the access to the data directly, the access to them is provided through the functions of the class. It is one of the popular feature of Object Oriented Programming(OOPs) that helps in data hiding.

Program:

#include<iostream.h>

#include<conio.h>

class emp

{

private:

int a,b,c;

public:

emp()

{

a=b=c=0;

}

void get()

{

cout<<”enter two number\n”;

cin>>a>>b;

}

void put()

{

c=a+b;

cout<<c;

}

};

void main()

{

emp a1;

a1.get();

a1.put();

getch();

}

Output:

Enter two number
