Create A Visual Logic Program To Read And Search Names

Create a Visual Logic program to read and search names from a file

The assignment requires creating a Visual Logic® program that involves file input/output processing, utilization of arrays, loops, and decision-making logic. Specifically, the program should read first names from a text (.txt) file into an array, prompt the user for names to search within the array, and provide appropriate messages based on whether a searched name exists. The process continues until the user indicates to stop.

Details include creating an array to store up to 100 first names, reading names from the file until the "LastOne" entry signifies the end of the list, and performing repeated searches based on user input. The program must utilize nested loops: an outer loop prompting for names until 'stop' is entered, and an inner loop searching the array for each name. Additionally, the program should handle the file properly and present clear output messages based on search results.

Paper For Above instruction

The task at hand is to develop a Visual Logic® program that efficiently manages file input/output operations, array handling, and decision-making processes to facilitate a dynamic name search application. This program demonstrates fundamental programming concepts, including reading data from external files, utilizing arrays for data storage, implementing nested loops for searching, and managing user interaction through input prompts.

The core functionality begins with reading first names from a text file into an array. The file, which contains names each enclosed in quotes, is processed line by line, with names stored sequentially in a predefined array capable of holding up to 100 names. An essential aspect is recognizing the special 'LastOne' marker, which indicates the end of valid data entries, ensuring that the program does not process beyond this point. Proper handling of file operations includes opening, reading, and closing the file reliably, as prescribed in the sample program references.

Once the names are loaded into the array, the program enters an interactive phase where it repeatedly prompts the user to enter a first name for searching. This process employs an outer loop, which continues to run until the user inputs 'stop', signaling the end of searches. Inside this loop, a nested inner loop scans the array for a match to the user-inputted name. If a match is found, the program displays a message confirming the occurrence; otherwise, it informs the user that the name was not found.

This nested loop structure ensures thorough searching within the array for each user query, emphasizing the importance of control flow in programming. It also underscores the concept of user-driven execution flow, providing real-time feedback based on the search results. Such an approach emphasizes clean code practices, including proper loop nesting, condition checking, and user communication.

Furthermore, attention must be given to efficiently handling both the file reading and user input procedures to avoid errors and ensure smooth program operation. The program's modular design, with clear separation between file processing, data searching, and user interaction, enhances readability and maintainability.

For completeness, the implementation should include generating the necessary files: a text file formatted with names in quotes, the Visual Logic® (.vls) file with the program logic, and packaging these files into a ZIP archive for submission, along with the Visual Logic® executable (.exe) and the .vls file. Proper adherence to the assignment requirements ensures a comprehensive demonstration of file I/O, data structures, loops, and decision-making capabilities in Visual Logic®.
