PLEASE write the code in C++. employee.h, employee.cpp, and hw09q1.cpp is given. Do not modify employee.h and answer the questions in cpp files. Array is used, not linked list. It would be nice if you could comment on the code so I can understand how you wrote it

Here is the answer for your question in C++ Programming Language.

Kindly upvote if you find the answer helpful.

NOTE : I have used dev-c++ to execute the code. Hence I had to include employee.cpp file instead of employee.h file in hw09q1.cpp file i.e., #include "employee.cpp". If including employee.h file works for you,please include that only.
