Help w/ input validation in function arrays

[boliviano3]

I'm having a couple of problems w/ getting the program to end when the user enters 'Q' after they've been asked if they want to try again. Also, after enter a negative int is entered for employee id then either the program moves to displayEmployeeInfo & shows the info that's been already entered or if no info had been entered it should skip displayEmployeeInfo altogether and just display the total payroll at zero. Sorry if I'm not explaining this well but here are the samples:

Sample Run:

Enter employee ID ====> -5

Total Payroll for this month: $0.00

Sample Run #3:

Enter employee ID ====> 123
Enter payroll status ====> t
*** Invalid payroll status ***
Do you want to try again or quit?
Type Q or q to quit, any other key to continue: U
Re-enter: 's' or 'S' for salaried, 'h' or 'H' for hourly,
'c' or 'C' for commissioned ====> x

*** Invalid payroll status ***
Do you want to try again or quit?
Type Q or q to quit, any other key to continue: x
Re-enter: 's' or 'S' for salaried, 'h' or 'H' for hourly,
'c' or 'C' for commissioned ====> H
Enter number of hours worked this month ====> 160

Enter employee ID ====> -9

Employee ID Payroll Status Gross Pay

123 Hourly $3000

Total Payroll for this month: $3000.00

Any help woould be greatly appreciated

Every time you enter any input, do you press the ENTER key? That key does go into the input buffer, ready for the next input. You need to clear it out.

[boliviano3]

I'm not sure I understand what you mean

[WaltP]

OK, I'll break it down. Every time you enter any input, do you press the ENTER key?

[boliviano3]

Yes, sorry for being a bit naive
