This assignment assumes you have completed Employee and ProductionWorker Classes.

Modify the Employee and ProductionWorker classes so they throw exceptions when the following errors occur:

The Employee class should throw an exception named InvalidEmployeeNumber when it receives an employee number that is less than 0 or greater than 9999.

The ProductionWorker class should throw an exception named InvalidShift when it receives an invalid shift.

The ProductionWorker class should throw an exception named InvalidPayRate when it receives a negative number for the hourly pay rate.

Write a driver program that demonstrates how each of these exception conditions works. For C++
