Final answer:
The question is about writing a program that manages customer account data using structures within an array, with operations for input, update, and display. This would involve defining a structure with relevant fields and implementing functions for user interactions.
Step-by-step explanation:
The student question pertains to writing a program in a programming language that manages customer accounts using a structure (equivalent to a record in some languages) within an array. The program should handle basic operations such as entering data, changing existing data, and displaying all account data.
This problem would typically involve implementing a menu system to allow the user to perform these operations, along with functions or methods that handle the interaction with the array of structures.
Example Structure Definition and Functionality
The structure would have fields for a customer's name, address, city, state, and ZIP, telephone number, account balance, and date of last payment. An array of at least 10 such structures needs to be declared to store multiple customer account data.
User interactions would include entering data into the array, which would involve asking the user for input and storing that input in the array. Changing the contents of any element would require selecting an array element and then updating the appropriate fields. Displaying all the data might involve iterating over the array and printing out the data for each structure in a human-readable format.
