b$).$ In a working $C++$ program. Create a base class named Point consisting of $x$ and $y$ data

members representing point coordinates. From this class, derive a class named Circle with

another data member named radius. For this derived class, the $x$ and $y$ data members

represent the circle's center coordinates. The member functions of the Point class should

consist of a constructor, an area$()$ function that returns $0,$ and a distance$()$ function that

returns the distance between two points, $(x,y)$ and $(x_2,y_2),$ where

distance $=\sqrt[\phantom{2}]{(x_2-x_1{)}^2+(y_2-y_1)}$

Additionally, the derived class should have a constructor and an override function named

area$()$ that returns a circle's area.

Have your prograin call all the member functions in each class. In addition, call the base

class's distance$()$ function with two Circle objects and explain the result this function

returns.
