C++ Modify your Project

to: 1. Replace Class with Structure for Employee and Department.

2. Inside each structure, replace all string variables with array of characters.

3. Make Employee and Department editable. That means, the user should be able to edit a given Employee and Department.

4. Do not allow the user to edit the Employee ID and Department ID.

5. Use Random Access Files to store the data in Binary Form.
