Hello there, I built most of the program but there are some errors in it, I would like you to fix them.
Also, Please read the grader notes and make the needed changes. Thank you
Here is my codes:https://codeshare.io/VZykxz
I added an image please see it to have an idea about the assignment!
Grader Notes:
- What employee ID should be entered? You don't have a method for getting this info.
- I like the use of the OOP principles here and the use of classes for each component—thisreally improves the efficiency and organization of the code.
- When entering the management/hr function, I entered admin123 and it went on an endlessloop
- Please be sure to include a header in the program.
