#include<iostream>
using namespace std;

class A
{
public:
	void display()
	{
		cout<<"A display"<<endl;
	}

};

class B : public A
{
public:
	void display()
	{
		cout<<" B display "<<endl;
	}
};

int main()
{
	B b1;
	b1.display();

	return 0;
}

In this program can you please tell me how can i access base class
method ie.,display() using derived class object.ie.,b1.

A single line has to be included in this main funtion.
