Overview of the final project:

In this final project you will create an employee database application by fulfilling the

requirements given below. You must first create the classes as described. Because this

final project is largely an extension of homework $4,$ you can copy your homework $4$ code

here or use the code provided by the homework $4$ solution when appropriate. Given that

there are more requirements and some different requirements for this final project, please

read the whole document carefully and adjust your previous code accordingly.

After creating the required classes, write a program that will use these classes to build an

application for an Employee Database. All employee data is stored in a file called

"empdata.dat". This file is provided and will be used to test your program $($don$\text{'}$t change

this file$).$ Each time you run the program, the user is allowed to repeatedly select from

the seven choices described below:

Add a new employee

Display employees' information

Compute and print the name and compensation of all employees

Search employees by name

Check basic statistics of employees

Calculate the reimbursement of one employee

Exit the application

The first time you execute the program, your file will have several employees in it$.$ They

are used to test your program. As you add employees to the program, it may contain more

employees. When you exit the application, all these employees will be stored in a new

data file. This setting doesn't reflect the real use case, but it fits the final project purpose
