Plz give an example with c++ language

What is the difference between abstraction,encapsulation,data hiding?Where they implemented in c++ ?
Abstraction means hiding complex details of creation(logic and functions) and just implenment/call them without bothering about how they work?.


Encapsulation means combining both data and function that operates on that data into a single unit(eg classes and objects in C++(or in any othe OPP).


Data Hiding means to make data invisible to external functions to minimize accidental modification/chage of important data. Following is the beast example of all the three





class employee /* Encapsultaion*/


{


private:


char name[20];


int age;


float salary;





public: /*Data Hiding, Following functions access data */


void getemployee


{


cout%26lt;%26lt; "Enter name";


cin%26gt;%26gt;name;


cout%26lt;%26lt;"Enter Age";


cin%26gt;%26gt;age;


cout%26lt;%26lt; "Enter Salary";


cin%26gt;%26gt;salary;


}


void showemployee


{





cout%26lt;%26lt;"\n Name"%26lt;%26lt;name;


cout%26lt;%26lt;"\n Age"%26lt;%26lt;age;


cout%26lt;%26lt;"\n Salary"%26lt;%26lt;salary;


}


};


void main()


{


/*Abstraction:- working defined in employee class*/





employee e1;


e1.getemployee();


e1.showemployee();


}
