help me fix this in order and please explain how it was done

In previous chapters, you have been developing a Fraction structure for Teachers 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 displayedthe 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.
