For this derived class, the x and y data members represent a circle’s centre coordinates. The member method of the Point class should consist of a constructor that set the value for x and y to 0, an area() method that return 0, and distance() method that returns the distance between two points, (x1,y1) and (x2,y2), where

Additionally, the derived class should has an overided method named area() that return’s a circle area

Area = 3.14 x radius2.
