Question
The All-Natural Wood Furniture Company has recently hired you to help them convert their manual payroll system to a computer-based system. Write a program to produce a 1-week payroll report for only one employee to serve as a prototype (model) for the administration to review. Input for the system will be the employee’s 4-digit ID number, the employee’s name, hours worked that week, and the employee’s hourly pay rate. Output should consist of the employee’s ID number, the employee’s name, the hours worked that week, the hourly rate, the gross pay, Federal withholding deduction based on an 18% tax rate, State withholding deduction based on a 4.5% tax rate, and net pay.
Use main( ) as the driver function. Allow the user to run the program as many times as desired.
Write 5 functions that main( ) calls to accomplish the task:getData( ): Prompts the user for an employee’s 4-digit ID #, the employee’s name, the hours worked that week, and hourly pay rate. Criteria for data validation:
Employee ID must be an integer between 1000 and 9999, inclusive. Do not allow user to enter an ID number out of this range.
Hours worked must be greater than zero and less than 120. Do not allow user to enter the amount of hours worked outside of this range.
Hourly Rate must be greater than zero. Do not allow the user to enter a zero or a negative pay rate.
computeGrossPay( ): Computes gross pay earned by employee. An employee working more than 40 hours per week is compensated at time-and-a-half for every hour over 40.
computeDeductions( ): Computes the Federal and State withholding deductions using the rates listed above.
computeNetPay( ): Calculates the net pay for the employee.
displayResults( ): Displays the employee’s ID#, the employee’s name, the hours worked, the hourly pay rate, gross pay, Federal withholding amount, State withholding amount, and Net Pay.
Sample Input/Output:
Please enter the employee's 4 digit ID # and press <Enter>
1468
