Important requirements for all questions: • All data members must be declared as “private” • No global variable is allowed to be declared and used • Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and return value instead. • “cin” and “cout” should be done in main() or any testing functions • Make sure that you clearly show how the C++ class, its methods and all the functions are being called at least twice and print out its return value and its results properly.
