C++ language question

Do Programming project 2 on page 697. The student may start with the attached code. Please notice that main function is given as well as several test functions. It is good idea to understand the main function and test functions first. When you implement the code, try to implement the functions are required for test 1 first. Commnent away the code in main function so that only test one part will be executed. After pass test one, then implement the functions that are required for test 2. This time, uncomment the code in main function that tests test 2. And so on. The program will tell you what is your grade for this program.

Define a class for rational numbers. A rational number is a number that be represented as the quotient of two integers. For example, 1/2, 3/4, 64/2, and so forth are all rational numbers. (By 1/2, etc., we mean the everyday meaning of the fraction, not the integer division this expression can would produce in a C++ program.) Represent rational numbers as two values of type int, one for the numerator and one for the denominator. Call the class Rational. Include a constructor with two arguments that can be used to set the member variables of an object to any legitimate values. Also include a constructor that has only a single parameter of type int; call this single parameter wholeNumber and define the constructor so that the object will be initialized to the rational number wholeNumber/1. Also include a default constructor that initializes an object to 0 (that is, to 0/1). Overload the input and output operators >> and  >=, +, -, , and /. Also write a test program to test your class. (Hints: Two rational numbers a/b and c/d are equal if a*d equals c*b. If b and d are positive rational numbers, a/b is less than c/d provided a*d is less than c*b. You should include a function to normalize the values stored so that, after normalization, the denominator is positive and the numerator and denominator are as small as possible. For example, after normalization 47-8 would be represented the same as -1/2. You should also write a test program to test your class.)
