(Rational Class) 1. Create a class called Rational (separate the files as shown in the chapter) for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private data of the class-the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default values in case no initializers are provided and should store the fraction in reduced form. For example, the fraction 2/4 would be stored in the object as 1 in the numerator and 2 in the denominator. Provide public member functions that perform each of the following tasks: Make an overloaded operator of the + symbol for the add method - Adds two Rational numbers. The result should be stored in reduced form. Make an overloaded operator of the - symbol for the subtract method - Subtracts two Rational numbers. Store the result in reduced form. Make an overloaded operator of the * symbol for the multiply method - Multiples two Rational numbers. Store the result in reduced form. Make an overloaded operator of the / symbol for the divide method - Divides two Rational numbers. The result should be stored in reduced form. NO CHANGES TO THIS (toRationalString - optional uses iostream from previous chapter - extra credit) - Returns a string representation of a Rational number in the form a/b, where a is the numerator and b is the denominator. NO CHANGES TO THIS | display - Display the Rational number a/b. NO CHANGES TO THIS | toDouble - Returns the Rational number as a double.
