Description
write a C++ program that consists of three classes, A,B, and C,such that B is a subclass of A and C is a subclass of B. Each class should define a member variable named "x" (that is, each has its own variable named x). Describe a way for a member function C to access and set A's version of x to a given value, without changing B or C's version.
