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
