Create a menu for the following tasks:

1. Add Customer Data

2. Show Existing Customer Data

3. Delete Customer Data 4. UnDelete Customer Data

X. Exit

Menu Item 1 should do the tasks originally done in Assignment 2.

Menu Item 2 should be a coded in a method showExistingCustomerData. It should read the "Customer.dat" file and display CustomerNumber, CustomerName and isDeleted.

Menu Item 3 should prompt for a Customer Number to delete. It should then read the Customer Data file and if a matching customer is found, it should changed the item isDeleted to Y and 'update' the file. If no customer number is found, it should display "Customer Number #### not found to delete.". ( ##### is the entered customer number). If the customer is already deleted, it should display "Customer is already deleted".

A note regarding 'updates'. You can rewrite the entire structure or use the file.seekp methods to do the updates.

Menu Item 4 should prompt for a Customer Number to un-delete. It should then read the Customer Data file and if a matching customer is found, it should changed the item isDeleted to N and 'update' the file. If no customer number is found, it should display "Customer Number #### not found to delete.". ( ##### is the entered customer number). If the customer is already not deleted, it should display "Customer is not already deleted"

Tips:This task may require you to change how the file is opened or optionally use additional file open and closes. Always confirm the file does not get deleted after a program restart.
