Employee Class Modify the Employee class: .Add an exception class: InvalidHireDate Add code to the Employee class to check if hire date string object fits the MM/DD/YYYY numeric format. One easy way to accomplish this is to use the "square brackets" operator [ ])to access individual characters in the hire date string: 1. The hire date string should have a length of 10 2. The characters at index 2 and index 5 should be a forward-slash character/). 3. The characters at index 0,1,3,4, 6,7, 8, and 9 should be in the range of 0. .9. (Refer to the isdigit () function in the cctype function library. You may need to add a #include statement to your program. (Refer to Chapter 10 of the textbook, or the cplusplus.com web-site.) ProductionWorker Class Modify the ProductionWorker class: Add two exception classes: InvalidShift, and InvalidPayRate. Add two new test functions: testShift(int shift) and testPayRate (double rate) Employee Class Modify the Employee class: .Add an exception class: InvalidHireDate Add code to the Employee class to check if hire date string object fits the MM/DD/YYYY numeric format.
