**Question description**

1. Create a class called Rational for performing arithmetic with fractions.

Classes and Object Programming

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 is 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 the object 1 in the numerator and 2 in the
denominator. Provide public member functions that perform each of the
following tasks:

a. Adding two Rational numbers by the function called addition. The result should be in reduced form.

b. Subtracting two Rational numbers by the function called subtraction. The result should be in reduced form.

c. Multiplying two Rational numbers by the function called multiplication. The result should be in reduced form.

d. Dividing two Rational numbers by the function called division. The result should be in reduced form.

e. Printing Rational numbers in the form a/b, where a is the numerator and b is the denominator.

f. Printing Rational numbers in floating-point format.

Write a main function to do the following:

a. Ask user to enter 2 fractions (4 integer number). Your program should do the error checking for denominator.

b. Continually display the menu for calculations until exit. Display the result for selected calculation.
