Answer to Question #274616 in C++ for Amit

Question

Create a class Data with data members: height and breadth of object given by the user and member functions get_data() to read the values and put_data() to display the values. Create another class Rectangle that inherits class Data and implement its methods area Rectangle() and perimeter Rectangle() that computes the area and perimeter of a rectangle. Create another class Triangle that inherits class Data and implement its methods area Triangle() and perimeter Triangle() that computes the area and perimeter of a triangle.
