Question

Create a program that presents a menu with these options:

1. Add employee
2. Print Employee Report
3. Quit

Read the initial employee list from a text file and store the employee information into a DICTIONARY called empDict. Key empID, value is a LIST that contains name, payrate, and hours.

The text file will be structured as shown below, where each line contains the employee id, employee name, payrate and hours. Each entry on the line is separated by a comma and a space.

Example textfile:

111, George Gray, 10, 40
222, Amy Abrahmson, 10, 30
333, David Dell, 10, 42
444, Bob Brown, 5, 40

Example of the empDict after the information shown has been readd and stored:
{ 111: [“George Gray”, 10, 40], 222: [“Amy Abrahmson”, 10,30], 333: [“David Dell”, 10, 42], 444:[“Bob Brown”,5,40] }

The program must contain the following functions:

• createMenu(optionList, menuTitle) à returns a string
• getValidChoice(numOptions, menuStr) à returns an integer
• addEmployee(empDict) à returns the updated dictionary.
           asks the user to enter id, name, payrate, and hours
          
           stores the information into the empDict
• printReport(empDict) à doesn’t return anything. Simply prints a report
  calculates grossPay -- overtime hours (above 40) receive 1.5 times the regular payrate

Example of the report for the data shown:

                                         Employee Roster

ID            Name                                    PayRate               Hours                    GrossPay
=================================================================

111         George Gray $10.00                   40                           $400.00
222        Amy Abrahmson $10.00                  30                           $300.00
333        David Dell                            $10.00                   42                           $430.00
444         Bob Brown                          $ 5.00   40                           $200.00
