1) Redo this as a SWITCH STATEMENT

2) Ask the user to provide a week's worth of high temperatures. You program will output the data in one line, in fields with 10 spaces, with 2 decimals of precision. It will also display the week's average high temperature and the day with the highest high temperature.

3) Ask the user to input an employee name, hours worked, base pay, overtime multiplier (time and a half, double time...), and tax rate. Use decision structures to determine if OT is calculated. Then, output the weekly earnings as gross and net pay. Format the output to 2 decimals.
