Could someone help me with this problem please?

[Bespin1138]

I am working on a project covering pages 459-466 of C++11 for Programmers by Paul and Harvey Deitel, using Microsoft Visual Studio Express 2013. It involves files ClientData.h, ClientData.cpp, Fig14_12.cpp, and Fig14_13.cpp. After I run the program using the code in Fig14_12.cpp, I am supposed to enter the following information that is stored into a credit.dat file involving account numbers, last names, first names, and balances:

37 Barker Doug 0.00
29 Brown Nancy -24.54
96 Stone Sam 34.98
88 Smith Dave 258.34
33 Dunn Stacey 314.33

0 (states that I am done entering the data)

After I enter the data mentioned above, I am supposed to replace the code in Fig14_12 with that of Fig14_13 so that the data is listed in order by account number. However, when I run the program, the only row that is listed is Account, Last Name, First Name, and Balance, but none of the profiles are displayed.

My only guess is that I have to save the program that I run in Fig14_12 after entering the client data, before I enter the code from Fig14_13. If that is the case, How do I save a running program in Microsoft Visual Studio Express 2013? If not, what am I doing wrong?

Thanks

Here are the codes.
