Question
A company wants you to write a C++ program that allows the user to input 10 employee names, hourly rate and hours worked into 3 arrays. Program should compute each employees gross pay, using tax withholding percentage as shown below; tax withholding amount, and net pay (gross pay minus tax withholding).
Display all the results for each employee. The end program should display the total of all hours worked, the total gross pay, the total tax withholding for all employees and total net pay.
Weekly Gross Pay Withholding Percentage
0.00 to 300.00 10
300.01 to 550.00 13
550.01 to 800.00 16
800.01 and up 20
