Chapter 20, Problem 20.15E
(Payroll System Modification) Modify the payroll system of Figs20.9.—20.17 to include additional Employee subclasses Pieceworker and Hourlyworker. A Pieceworker represents an employee whose pay is based on the number of pieces of merchandise produced. An HourlyWorker represents an employee whose pay is based on an hourly wage and the number of hours worked. Hourly workers receive overtime pay (1.5 times the hourly wage) for all hours worked in excess of 40 hours.
Class Pieceworker should contain private instance variables wage (to store the employee’s wage per piece) and pieces (to store the number of pieces produced). Class Hourlyworker should contain private instance variables wage (to store the employees wage per hour) and hours (to store the hours worked). In class Pieceworker, provide a concrete implementation of method earnings that calculates the employee’s earnings by multiplying the number of pieces produced by the wage per piece. In class Hourlyworker, provide a concrete implementation of method earnings that calculates the employee’s earnings by multiplying the number of hours worked by the wage per hour. If the number of hours worked is over 40, be sure to pay the HourlyWorker for the overtime hours. Add a pointer to an object of each new class into the

C++ Project ( Build the requested system 100% into a C++ environment, excluding Class framework & All defined variables must be represented as pointer type, int, char etc)Scenario:A bookshop (PRIMER BOOKSHOP) wants to maintain the inventory of books that are being sold at the shop. The list includes details such as author, title, price, publisher, and stock position. Whenever a customer wants a book, the sales personnel inputs the title and author, and the system searches the list and displays whether it is available or not.- If it is not, an appropriate message is displayed.- If it is, then the system displays the book details and requests for the number of copies required.- If it is requested, copies of the book details and requests for the number of copies required are available, the total cost of the requested copies is displayed and your system needs to update the database.- Sales personnel, from time to time are allowed to update the latest stock and price to the created…
(Richer Shape Hierarchy) The world of shapes is much richer than the shapes included inthe inheritance hierarchy of Fig. 19.3. Write down all the shapes you can think of—both two-dimensional and three-dimensional—and form them into a more complete Shape hierarchy with asmany levels as possible. Your hierarchy should have the base class Shape from which class TwoDimensionalShape and class ThreeDimensionalShape are derived. [Note: You do not need to write any codefor this exercise.] We’ll use this hierarchy in the exercises of Chapter 20 to process a set of distinctshapes as objects of base-class Shape. (This technique, called polymorphism, is the subject ofChapter 20.)
Problem description:
(Malik,2017) Programming Exersices Problem 16, pág. 740, Cap 10 Write the definition of a class, swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time.

- ) Define a struct type to represent a university student with a name, surname, course, year. 2) Define a couple of named instances, e.g., David, Pearl, Computing, Year1. 3) Apply selector function to return the course and year of your student.4) Write a function that updates the year of a student, i.e. if year is “Year1”, then update to “Year2”, if year is “Year2”, then update to “Year3”, if the year is “Year3” then updated to “Graduated”. Make sure to write what the difference between mutable and immutable is.arrow_forward(Modifying Class GradeBook) Modify class GradeBook (Figs. 16.11–16.12) as follows:a) Include a second string data member that represents the course instructor’s name.b) Provide a set function to change the instructor’s name and a get function to retrieve it.c) Modify the constructor to specify course name and instructor name parameters.d) Modify function displayMessage to output the welcome message and course name,then the string "This course is presented by: " followed by the instructor’s name.Use your modified class in a test program that demonstrates the class’s new capabilities.arrow_forward(Time Class Modification) It would be perfectly reasonable for the Time class of Figs. 17.4–17.5 to represent the time internally as the number of seconds since midnight rather than the threeinteger values hour, minute and second. Clients could use the same public methods and get thesame results. Modify the Time class of Fig. 17.4 to implement the time as the number of secondssince midnight and show that there is no visible change in functionality to the clients of the class.[Note: This exercise nicely demonstrates the virtues of implementation hiding.]arrow_forward
- (Payroll System Modification) Modify the payroll system of Figs. 20.9–20.17 to includeprivate data member birthDate in class Employee. Use class Date from Figs. 18.6–18.7 to representan employee’s birthday. Assume that payroll is processed once per month. Create a vector of Employee references to store the various employee objects. In a loop, calculate the payroll for each Employee (polymorphically), and add a $100.00 bonus to the person’s payroll amount if the currentmonth is the month in which the Employee’s birthday occurs.arrow_forwardProgramming Exercise C++ Summary During the tax season, every Friday, the J&J accounting firm provides assistance to people who prepare their own tax returns. Their charges are as follows: If a person has low income (<= 25,000) and the consulting time is less than or equal to 30 minutes, there are no charges; otherwise, the service charges are 40% of the regular hourly rate for the time over 30 minutes. For others, if the consulting time is less than or equal to 20 minutes, there are no service charges; otherwise, service charges are 70% of the regular hourly rate for the time over 20 minutes. (For example, suppose that a person has low income and spent 1 hour and 15 minutes, and the hourly rate is $70.00. Then the billing amount is 70.00 X.40 X (45/60) = $21.00.) Instructions Write a program that prompts the user to enter yearly income, the hourly rate, the total consulting time. The program should output the billing amount.

These cells are represented by elements on a grid of squares, where a grid has an arbitrary size. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squares that contain other cells. The rules are stated as follows: 1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation. Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation. Write a program that simulates this game and displays all successive…arrow_forward
