Rational Arithmetic II

Modify the class Rational of Programming Challenge 8 to add overloaded operators +, -, *,

and / to be used for addition, subtraction, multiplication, and division. Test the class by reading

and processing from the keyboard (or from a file) a series of rational expressions such as

2 / 3 + 2 / 8

2 / 3 * – 2 / 8

2 / 3 – 2/ 8

2 / 3 / 2 / 8

To facilitate parsing of the input, you may assume that numbers and arithmetic operators

are separated by whitespace.
