Textbook Question
Chapter 10, Problem 1CP
In Chapter 9, you created a Contestant class for the Greenville Idol competition. The class includes a contestant’s name, talent code, and talent description. The competition has become so popular that separate contests with differing entry fees have been established for children, teenagers, and adults. Modify the Contestant class to contain a field that holds the entry fee for each category, and add get and set accessors.
Extend the Contestant class to create three subclasses: ChildContestant, TeenContestant, and AdultContestant. Child contestants are 12 years old and younger, and their entry fee is $15. Teen contestants are between 13 and 17 years old, inclusive, and their entry fee is S20. Adult contestants are 18 years old and older, and their entry fee is $30. In each subclass, set the entry fee field to the correct value, and override the Tostring() method to return a string that includes all the contestant data, including the age category and the entry fee.
Modify the GreenvilleRevenue
• The program prompts the user for the number of contestants in this year’s competition, which must be between 0 and 30. The program continues to prompt the user until a valid value is entered.
• The program prompts the user for names, ages, and talent codes for the contestants entered. Along with the prompt for a talent code, display a list of valid categories. Based on the age entered for each contestant, create an object of the correct type (adult, teen, or child), and store it in an array of Contestant objects.
• After data entry is complete, display the total expected revenue, which is the sum of the entry fees for the contestants.
• After data entry is complete, display the valid talent categories and then continuously prompt the user for talent codes, and display all the data for all the contestants in each category. Display an appropriate message if the entered code is not a character or a valid code.

Create a class called Student that includes a data member that holds a name for each object created from the class and a data member that represents the number of students. That is, the first object created will be 1, the second 2, and so on.To do this, you’ll need another data member that records a count of how many objects have been created so far. (What keyword specifies this?) Then, as each object is created, its constructor increase the count member variable by one.Then write a main() program that creates three objects and queries each one about their names and the count.
Class Design
Within the backend server, we’ll have multiple classes to organize our code.
All the class descriptions are listed below.
FoodWastageRecord
NOTE: You need to design this class.
It represents each food wastage entry recorded by the user through the form on the webpage (frontend).
If you notice the form on the webpage, you’ll see that each FoodWastageRecord will have the following as the data members aka member variables.
Date (as string)
Meal (as string)
Food name (as string)
Quantity in ounces (as double)
Wastage reason (as string)
Disposal mechanism (as string)
Cost (as double)
Each member variable comes with its accessor/mutator functions.
FoodWastageReport
NOTE: You need to design this class.
It represents the report generated on the basis of the records entered by the user. This class will be constructed with all the records entered by the user as a parameter. It will then apply the logic to go over all the records and compute the following:

Demonstrate Book Class in a Tester Program with an object of Book class.

- You will create a couple of classes that could be used to create a Text Adventure game. The class will be called "Item" and will represent an item in the game that can be carried and used by a player (such as a weapon or a tool). The Item Class The Item class will have only one property: A string description. The Item class will have exactly 3 methods: There will be a default constructor that takes no parameters. This constructor will give a generic, default description of the Item. There will be a constructor that takes a string parameter, and it will initialize the Item's description based on the parameter. There will be a method called "print" that will print the Item's description to standard output. PLEASE MAKE SURE ITS POSSIBLE TO COMPILE WITH THIS CODE.

All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction.Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator.
