/**
* User is prompted to enter the first and last name of an employee after
* the hourly payroll system is engage. Prompt for hours worked. Error messages
* and re=prompts are displayed as long as hours worked is greater than 40 or less
* than 5. The pay rate is prompted. Error messages and re-prompts are displayed
* as long as the pay rate is less than minimum wage or greater than 26. Lastly
* the employees 401(k) distribution percentage is prompted. Error message and
* re-prompt or displayed as long as the contribution percentages is greater than 10.
* After the correct entries are made, the gross pay is calculated along with the
* contribution to the 401(k). Totals or girls pay in 401(k) are accumulated.
* And if-else determines the printing of the $ sign for the first employee.
* The if-else also adds the employee information to the payroll expense report.
* The user is then asked whether or not to continue. If the user says ‘yes’,
* then the whole process begins again for the next employee. If the user says
* ‘no’ then the TOTALS line is added to the report and the report is printed.
