Design and implement a program that defines a base class A, which has a subclass B, which itself has a subclass C. The A class must implement a method, which is overridden in both B and C. Write the same program in two different languages (C++ and Ruby) Write a test class that instantiates A, B, and C Your program should include three calls to the method. One of the calls must be statically bound to As method. One call must be dynamically bound to Bs method, and one must be dynamically bound to Cs method. All of the method calls must be through a pointer to class A.
