Create an application class named LetterDemo that instantiates objects of two classes named Letter and CertifiedLetter and that demonstrates all their methods. The classes are used by a company to keep track of letters they mail to clients. The Letter class includes auto-implemented properties for the name of the recipient and the date mailed. Also, include a ToString() method that overrides the Object classs ToString() method and returns a string that contains the name of the class (using CetType and the Letters data field values. Create a child class named CertifiedLetter that includes an auto-implemented property that holds a tracking number for the letter.

In Chapter 9, you created a Contestant class for the Greenville Idol competition. The class includes a contestants 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 program so that it performs the following tasks: The program prompts the user for the number of contestants in this years 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.
Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project. Modify the Rectangle class to use Double variables rather than Integer variables. Change the name of the GetArea method to GetAreaSqFt. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.

Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.
Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

Each of the following projects in the Chapter.03 folder of your downloadable student files has syntax and/or logical errors. In each case, immediately save a copy of the project folder with a new name that begins with Fixed before you open the project in Visual Studio. For example, the project folder for DebugThree1 will become FixedDebugThree1. All the files within the folders have already been named with the Fixed prefix, so you do not need to provide new filenames for any of the files in the top-level folder. After naming the new folder, open the project, determine the problems, and fix them. a. DebugThree1 b. DebugThree2 c. DebugThree3 d. DebugThree4
Some of the characteristics of a book are the title, author(s), publisher, ISBN, price, and year of publication. Design a class bookType that defines the book as an ADT. Each object of the class bookType can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock. To keep track of the number of authors, add another member variable. Include the member functions to perform the various operations on objects of type bookType. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is the same as the actual title of the book. Similarly, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock. Add similar operations for the publisher, ISBN, book price, and authors. Add the appropriate constructors and a destructor (if one is needed). Write the definitions of the member functions of the class bookType. Write a program that uses the class bookType and tests various operations on the objects of the class bookType. Declare an array of 100 components of type bookType. Some of the operations that you should perform are to search for a book by its title, search by ISBN, and update the number of copies of a book.
