Write a menu-driven program to manage a membership list. Assume that the names and phone numbers of all members are stored in alphabetical order (by last name and then by first name) in the text file MemberPhones.txt. Each record consists of two fields – a name field and a phone field. The names should appear in a list box when the form is loaded. When a name is highlighted, both the name and phone number of the person should appear in the text boxes at the bottom of the form.

To delete a person, highlight his or her name and click on the Delete option from the Update menu. To change either a person’s name or phone number, make the corrections in the text boxes and click on the Modify menu option. To add a new member, type his or her name and phone number into the text boxes and click on the menu option Add. When the Exit menu button is clicked, the new membership list should be written to the file and the program should terminate.

The development of a menu-driven program to manage a membership list embodies a fundamental application of file handling, user interface design, and data management. Such a program ensures efficient management of member information by allowing users to add, modify, or delete records, all while maintaining data integrity and order. This paper explores the essential components, design considerations, and implementation strategies necessary to build an effective membership management system, focusing on user interaction, data storage, and synchronization between the interface and the data file.

At its core, the program should initialize by reading from a text file named "MemberPhones.txt," which contains a list of member records sorted alphabetically by last name and first name. Each record comprises two fields: a name and a phone number. During program startup, these records are loaded into a list box component in the user interface, providing a visual overview of all members in order. When the form loads, the first member in the list should be automatically selected, and their details displayed in dedicated text boxes for name and phone number, enabling quick viewing and editing.

Data consistency and user convenience are critical aspects addressed in the interface design. Highlighting a name in the list box updates the content of the text fields to show the corresponding name and phone number, facilitating easy modifications. Users can add new members by entering the name and phone number into the text boxes and selecting the Add option from the menu. This action inserts the new record into the list, maintaining the alphabetical order, and updates the underlying file to ensure persistent storage.

The deletion process is straightforward: users highlight the desired member in the list box and select the Delete option from the menu. This removes the record from both the list box and the in-memory data structure, with the change reflected in the file upon termination. Modifying an existing record involves editing the details in the text boxes and clicking the Modify menu option, which updates the in-memory list and maintains the sorted order.

When the user chooses to exit the program via the Exit menu button, the current state of the membership list, including all modifications, should be written back to "MemberPhones.txt," ensuring data persistence across sessions. Proper error handling and data validation are also essential, such as checks for duplicate entries, invalid input formats, or empty fields, to promote data accuracy and prevent runtime errors.

Implementing this system requires a combination of file I/O operations, event-driven programming, and user interface controls common in desktop application development environments. Efficient algorithms for maintaining sorted lists upon insertion or deletion enhance performance, especially as the membership list grows. Overall, this program provides a practical example of CRUD (Create, Read, Update, Delete) operations integrated with file management and graphical user interfaces for professional, reliable data management applications.
