This assignment involves improving your assignment #6 by adding the ability to walk through the database (CustomerDB) using startWalk and continueWalk.

The customer database class ("CustomerDB.h" and "CustomerDB.cpp") must change:

• You need to add startWalk and continueWalk to your class.
  • These methods should behave like those in Chapter 9, except that they will "return" a customer object.
  • Adding these methods requires other changes (outside of these methods) in both the header file and the implementation file.
  • If a walk is interrupted by the invocation of any method that changes the class, any attempt to continue the walk must cause your program to quit.

The updated main program is provided (a7main.cpp). While you can use your Customer class ("Customer.h" and "Customer.cpp") from assignment #6, it's strongly recommended that you use those from the sample solution to ensure that your CustomerDB class is consistent with our Customer class as the TAs will use our Customer class for testing.

Refer to the sample executable if you have any questions.

Submit files "CustomerDB.h" and "CustomerDB.cpp".

Note that assignment #8 will be re-doing assignment #7 with a dynamically allocated array, and assignment #9 will be re-doing it with a linked list.
