* enter employee's name

* enter employee's base hourly pay

* enter the number of hours worked for the week

* error if hours worked exceeds 168 hours

* determine if employee is full-time or part-time

*****federal tax 3.5%

*****state tax 1.75%

*****social security 5%

*****health ins $100.00

*****dental ins $30.00

*****retirement 8%

if hours work is less than 40 then do not deduct health ins, dental ins, and retirement should be 4%

**use loop to enter additional employee's information until you enter keyword of "Exit" in employee's name-which should also terminate program

** use both if(if/else) and case code to make decisions based on program

** output should result to output file of SalaryInformaion.txt
