1.Write a C++ program A4p2.cpp with a class of your own design. The class should contain a protected int 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 integer 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 functions output sequence should be 6,3,10,5,16,8,4,2,1.) In your main function create an object of this class whose member var should be initialized with the first command line argument (that is, argv[1]) and then call the play member function to output the sequence of desired integers. You can check whether the supplied first command line argument is an integer between 1 and 50 in the main function.

2. Write a C++ program A4p3.cpp with a class that is a derived class of the class in problem 2. Add a private int member var2 to this class. Initialize the member variables var and var2 with a value between 1 and 50 using a constructor that takes two integer parameters. Add a public member function called getgcd that should print out the greatest common divisor of var and var2. (You can refer to gcd.c in Folios sample codes directory for how to compute the greatest common divisor of two integers.) In your main function, create an object of this class, initialize the members var and var2 with the first two command line arguments (that is, argv[1] and argv[2]) and then call the play and getgcd functions.

3. supply a makefile to compile the program.
