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.
Design a class named Month. The class should have the following private members: • name - A string object that holds the name of a month, such as "January", "February", etc. • monthNumber - An integer variable that holds the number of the month. For example, January would be 1, February would be 2, etc. Valid values for this variable are 1 through 12. In addition, provide the following member functions: • A default constructor that sets monthNumber to 1 and name to "January." • A constructor that accepts the name of the month as an argument. It should set name to the value passed as the argument and set monthNumber to the correct value. • A constructor that accepts the number of the month as an argument. It should set monthNumber to the value passed as the argument and set name to the correct month name. • Appropriate set and get functions for the name and monthNumber member variables. • Prefix and postfix overloaded ++ operator functions that increment…
11. PayrollDesign a PayRoll class that has data members for an employee’s hourly pay rate, number of hours worked of type double. The default constructor will set the hours worked and pay rate to zero. The class must have a mutator function to set the pay rate for each employee and hours worked. The class should include accessors for both the hours worked and the rate of pay. The class should lastly have a getGross function that will return a double calculated by multiplying the hours worked by the rateof pay.Write a program with an array of seven PayRoll objects. The program should ask the user for the rate of pay for each employee and the number of hours each employee has worked. Be sure to include an employee claiming to work more then 60 hours per week. Print out, the array number of the employee, the hours worked, the rate of pay, and the gross pay, of all the employee's each on their own line. Set the precision for printing the doubles to two decimal places.Input Validation: Do…

Design an Employee class that has fields for the following pieces of information:• Employee name• Employee numberNext, design a class named ProductionWorker that extends the Employee class. The ProductionWorker class should have fields to hold the following information:• Shift number• Hourly pay rateThe workday is divided into shifts: day and night. The shift field will hold an int value representing shift that the employee works. The day sifts is shift 1 and the night shift is shift 2. Design the appropriate accessor and mutator methods for each class.Once you have designed the classes, design a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s fields. Store the data in the object and then use the object’s accessor methods to retrieve it and display it on the screen.Program Sample Run #1The worker name is John RobinsThe worker number is 1234The shift is 1The rate is 36.0
