Single Level Inheritance

Program to demonstrate Single Level Inheritance :-

#include<iostream.h>

#include<conio.h>

class base

{

int a,b;

public:

void base_get()

{

cout<<"\nEnter Value of A: ";

cin>>a;

cout<<"\nEnter Value of B: ";

cin>>b;

}

void base_show()

{

         cout<<"\nBASE CLASS DATA ";

cout<<"\nA = "<<a;

cout<<"\nB = "<<b;

}

};

class derived:public base

{

int p,q;

public:

void derived_get()

{

cout<<"\nEnter Value of P:  ";

cin>>p;

cout<<"\nEnter Value of Q:  ";

cin>>q;

}

void derived_show()

{

cout<<"\nDERIVED CLASS DATA ";

cout<<"\nP=  :"<<p;

cout<<"\nQ=  :"<<q;

}

   };

void main()

{

derived d;

d.base_get();

d.derived_get();

d.base_show();

d.derived_show();

getch();

}
