INPUTS: Number of Hours Worked........................ a positive number OUTPUTS: Total Pay Earned................................... a positive number PROCESS: The Total Pay Earned is computed as $7.32 per hour for the first eight hours worked each day. Any hours worked beyond the first eight are billed at $11.73 per hour. ERROR HANDLING: The input Number of Hours Worked must be a positive real number. If it is a negative number or other nonacceptable character, the program will force the user to reenter the information. TESTING PLAN:INPUTOUTPUTNOTES 88*7.32Testing positive input 33*7.32Testing positive input 128*7.32 + 4*11.73Testing overtime input –6–6 Error message/ask user to reenter value Handling error

7. Either figure regular pay or pay with overtime main_function { real hours_worked, pay; write "Input the hours worked"; read hours_worked; if (hours_worked <= 8.0) pay = hours_worked * 7.32 else pay = 8 * 7.32; pay = pay + (hours_worked-8)*11.73; endif; write "Total Pay = ", pay; } Allocate Space in Memory for two Variables Interact with the User Test the User's Input Output Answer What happens when negative Hours Worked is entered?
