Implement Random Access Binary Files. Do Not use Arrays instead write the data directly to Random Access Binary File. New program should be modified to display a menu for the user to do the following: 1. Replace Employee and Department classes with Employee and Department Structures. 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. This means, you should not use an Arrays to store the data in the memory. Instead, when the user wants to create a new Employee/Department, you write it to the file right away. Also when the user says he/she wants to edit an Employee/Department, ask the user to enter EmployeeID/DepartmentID. Read the data from the file and display it to the user. Allow the user to enter new data and write it back to the file in the same position inside the file.(C++).
