Question

I was told to write just the function. Did I do that?

Question 9. Write a base class called Rectangle, which has two private member variables length and width. Write a constructor functions to set the values of width and length of the rectangle and also a function called area, where you calculate the area of the rectangle. Next derive a class called Square from Rectangle. Note that square has no member variable rather it uses the member variable from   base class rectangle. Write constructor for this class and also provide a function called areaSquare to calculate area of square

class shape {

protected:

                        int width, height;

                public:

                        shape(int a=0, int b=0)

{

Width =a;

Height=b;

}

Cout<<”Parent class area”<<endl;

Explanation / Answer

class Rectangle
{
int ar,length,breadth;
Rectangle( )
{
length=10;
breadth=20;
}
Rectangle(int l, int b)
length=l;
breadth=b;
}
void area( )
{
ar=length*breadth;
System.out.println(” “+ar);
}
public static void main(String args[ ])
{
Rectangle r1=new Rectangle( );   

Rectangle r2=new Rectangle(15,15);
System.out.println(“Area of rectangle with default constructor is: “);
r1.area( );
System.out.println(“Area of rectangle with parameterized constructor is: “);
r2.area( );
}
}

I did this with parametrized constructor also so take a look afterthis
