Implement the following hierarchy using C++ classes. 1. Shape: This should be an interface class that supports area() and display() functions. 2. Circle and Rectangle: Implement the area and display functions of Shape. 3. Quadrilateral: This class should be an abstract class. It may contain member variables for length and height. 4. Trapezoid: Should inherit length, height from Quadrilateral, and add 'side', which represents the side parallel to 'length'. 5. Create appropriate .h/.cpp files with constructors and destructors (wherever needed).
