Question

Wap to create Shape class. It has two data member function. area() and display(). Area is dummy function. And Display only working. And derived another class Circle. Which also two member function area() display1(). By using abstract class display area of circle and as well as display function of Base class

Answer 1

#include<iostream>
#include<string>


using namespace std; 


//class shape
class Shape
{
public:
	virtual void display()
	{
		
	}
	virtual float area(){
		return 0;
	}
};


//class Circle inheriting class Shape
class Circle: public Shape
{
private:
	float radius;
public:
	Circle(float radius){
		this->radius=radius;
	}


	void setRadius(float radius){
		this->radius=radius;
	}
	float getRadius(){
		return this->radius;
	}
	void display()
	{
		cout<<"Circle radius: "<<this->radius<<"\n";
		cout<<"Circle area: "<<this->area()<<"\n";
	}
	float area(){
		return 3.14*this->radius*this->radius;
	}
};






void main()
{
	
	Shape *s;
	Circle c(5);
	s=&c;
	s->display();


	int k;
	cin>>k;
}
