show a C++ program A4p2.cpp with a class of your own design.

show a C++ program A4p2.cpp with a class of your own design. The class should contain a protected int member variable var, which is initialized with an integer value between 1 and 50 in a constructor that takes an integer parameter. The class should contain a public member function called play that should print out a sequence of integers as a result of iteratively applying a math function f to the member variable var. The function f is defined as f(x)=3x+1 if x is odd and f(x)=x/2 if x is even. Stop the iteration when the value 1 is reached. (Example: When var is 6, the play function's output sequence should be 6,3,10,5,16,8,4,2,1.) In your main function show an object of this class whose member var should be initialized with the first command line argument to your program (i.e., argv[1]) and then call the play member function to output the corresponding sequence of integers. You can check whether the supplied first command line argument is an integer between 1 and 50 in your main function. A sample run can look like the following picture.
