Above is the code that was posted by an expert in response to my question. When I run the code above, my program isn't functioning correctly. There are no errors in the error box, and I created the records and temp files (I changed them to .txt instead of .dat). But, when I run the code and enter a menu choice, the program aborts. I don't know what's wrong with it. (I had to change the format in order to post the question.)

16. Customer Accounts his program should be designed and written by a team of students. Here are some suggestions One student should design function main, which will call other program functions The remainder of the functions will be designed by other members of the team The requirements of the program should be analyzed so each student is given about the same workload Write a program that uses a structure to store the following data about a customer account: Name Address City, State, and ZIP Telephone Number Account Balance Date of Last Payment The structure should be used to store customer account records in a file. The program should have a menu that lets the user perform the following operations: .Enter new records into the file. Search for a particular customer's record and display it . Search for a particular customer's record and delete it. Search for a particular customer's record and change it. e Display the contents of the entire file. Input Validation: When the data for a new account is entered, be sure the user enters data for all the fields. No negative account balances should be entered
