//Title      :Test Program 
//Description:
//            This is a test program for the class Rational.Class Rational provides memeber functions for 
//            performing arithmetic operations on Rational numbers.This test program allow the user to 
//            enter Rational numbers.It uses the functions of the Rational class to determine the maximum 
//            and sum of the Rational numbers entered by the user.It converts each rational number to its 
//            lowest fraction and prints each Rational number as a string using the function toString of 
//            the Rational class. 
//Inputs     :The numerator and denominator of each rational element as enterd by the user
//Outputs    :The List of all rational elements entered by the user.Each element is printed as a string
//           :The sum of all rational elements entered by the user
//           :The maximum of all rational elements entered by the user
//Local 
//  Variables:
//            rationale,rationstr-instances of Rational class
//            int RationalArray[]-the array which holds the rational numbers
//            int MAXARRAY-number of rational numbers to be entered by the user
//            int ACTUALMAXARRAY-The totla no of numbers to be entered by the user.
//            int ArrayIndex-position of Rational element in the array
//            int counter-counts the number of Rational elements
//            SumofRationalElements-instance of rational class-holds the sum of all rational elements
//                      entered by the user
//            MaxofRationalElements-instance of Rational class-holds the maximum of all rational elements 
//                      entered by the user
