Question

The following code can use loops, strings, arrays, functions, and classes. The code must be able to accept and perform operations on the whole number portion of a mixed number (like the '2' in 2 1/2):

In previous chapters, you have been developing a Fraction structure for Teacher’s Pet
Software. Now you will develop a class that contains the fields and functions that a Fraction
needs. Create a Fraction class with three private data fields for whole number, numerator,
and denominator. Also create a constant static public field to hold the symbol that separates a
numerator and denominator when a Fraction is displayed—the slash. Create three public
member functions for the class, as follows:
» An enterFractionValue()function that prompts the user to enter values for the
Fraction. Do not allow the user to enter a value of 0 for the denominator of any
Fraction; continue to prompt the user for a denominator value until a valid one is
entered.
» A reduceFraction()function that reduces a Fraction to proper form. For example,
a Fraction with the value 0 2/6 would be reduced to 0 1/3 and a Fraction with the
value 4 18/4 would be reduced to 8 1/2.
» A displayFraction()function that displays the Fraction whole number, numerator,
slash, and denominator.
Add any other functions to the Fraction class that will be useful to you. Create a main()
function that declares a Fraction object, and continues to get Fraction values from the
user until the user enters a Fraction with value 0 (both the whole number and numerator
are 0). For each Fraction entered, display the Fraction, reduce the Fraction, and display
the Fraction again.
