Define an abstract base class Point that includes protected data members for the (x, y) position of a shape, a public method to move a shape, and a public abstract method show() to output a shape. Derive subclasses- line, circle, and rectangle. You can represent a line as two points, a circle as a center and a radius, and a rectangle as two points on diagonally opposite corners. Test the classes by selecting ten random objects of the derived classes, and then invoking the show() method for each.
