Define an abstract base class SHAPE 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 for lines, circles and rectangles. Also define the class POLYLINE with SHAPE as the base class. You can represent a line as two points, a circle as a center and a radius. A rectangle as two points on diagonally opposite corners. Implement the toString() method for each class.Test the classes by selecting ten random objects of the derived classes, then invoking the show() method for each class.Use the toString() method in the derived classes.

Pure Abstract Base Class Project. Define a class called BasicShape which will be a pure abstract class. The class will have one protected data member that will be a double called area. It will provide a function called getArea which should return the value of the data member area. It will also provide a function called calcArea which must be a pure virtual function. Define a class called Circle. It should be a derived class of the BasicShape class. This...
