Answer to Question #213029 in C++ for Hemambar

Question

 Create a class Rational whose object can store a rational number. (For ex: ¾). Include the necessary constructors to initialize the objects and function to display the rational number in x/y format. Define the following non-member functions. 

addRational(Rational r1, Rational r2) : which should return a summation of the two input rational numbers r1 and r2. 

mulRational(Rational r1, Rational r2) : which should return the product of the r1 and r2. Set these two functions as friend to the Rational class 

Main function to read two rational numbers and display the sum and product of the input by calling the proper functions
