Question

The following can use loops, strings, arrays, and functions. The code must be able to accept and perform calculations on the whole number portion of a mixed number if necessary (as in the '2' in 2 1/4):

You are developing a Fraction structure for Teacher’s Pet Software. The structure contains
three public data fields for whole number, numerator, and denominator. Using the same
structure, write the functions described below:
» An enterFractionValue()function that declares a local Fraction object and
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. The function returns a data-filled
Fraction object to the calling function.
» A reduceFraction()function that accepts a Fraction object and reduces it to proper
form, returning the reduced Fraction. For example, a Fraction entering the function as 0
2/6 would be reduced to 0 1/3, and a Fraction entered as 4 18/4 would be reduced to 8 1/2.
» A displayFraction()function that displays any Fraction object passed to it. This
function displays a fraction with a slash between the numerator and denominator.
» 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
the numerator are 0). For each Fraction entered, display the Fraction, reduce the
Fraction, and display the Fraction again.
