Create a menu-driven, console application that reads data from a text file containing information about books, stores the data in a linked list, and sorts the books alphabetically. The program should initialize by creating the linked list from the file, which contains 3500 books, each with fields: author, title, publisher, description, ISBN, and year published. Upon startup, display a welcome message with the current date and present a menu with options to add new books (which updates both the list and the text file), remove specific books (from both list and file), remove all books (delete the list), sort the list by author using insertion sort, and search for books by author, title, or ISBN using sequential search.

Paper For Above instruction

Creating an efficient and user-friendly library management system that can handle a vast collection of books requires thoughtful planning and implementation in C++, especially when using Visual Studio 2017/2019. This system aims to facilitate easy cataloging, retrieval, and management of books through a menu-driven console interface, which interacts with a text file serving as persistent storage.

Introduction

The integration of data structures like linked lists combined with sorting and searching algorithms forms the backbone of effective library management software. The primary objective here is to build a robust application that reads books data from a text file, manages operations such as addition, deletion, sorting, and searching, and updates the file accordingly. Given the large volume of data (around 3,500 books), performance considerations, such as efficient sorting and searching techniques, are crucial.

System Design and Data Structures

The chosen data structure for this project is a singly linked list, where each node represents a book, encapsulating the six fields: author, title, publisher, description, ISBN, and year published. Linked lists are suitable for dynamic storage, ease of insertion and deletion, and flexible memory usage, which is advantageous given the possibility of frequent updates. Each node links to the next, facilitating traversal during operations like search and sort.

Reading Data from Text File

At startup, the program opens the text file, reads sequentially, and creates a linked list accordingly. Each book's data spans multiple lines, with each field stored on a separate line. The program reads each set of lines to instantiate a node and appends it to the linked list. This process ensures that all existing data is loaded into the program’s memory for manipulation during the session.

Implementing Core Operations

Adding a New Book

The system prompts the user to input all book details, creates a new node, adds it to the linked list, and appends the new data to the text file. It's essential to maintain data consistency by updating both in-memory structures and persistent storage.

Removing a Book

The delete operation involves searching for the book by a unique identifier (like ISBN), removing the corresponding node from the linked list, and updating the text file by rewriting it without the removed book. The user is prompted to select or input the identifying attribute for deletion.

Removing All Books

This function deletes the entire linked list, freeing associated memory, and truncates or deletes the content of the text file, effectively resetting the database.

Sorting Books by Author

To sort books alphabetically by author, the program first reads data from the file to construct a linked list, then applies an insertion sort algorithm. Insertion sort is suitable due to its stability and efficiency for relatively small or nearly sorted datasets; however, for large datasets, alternative algorithms like merge sort might be considered in practice.

Searching Books

Searching operations—by author, title, or ISBN—use sequential search given the potentially unsorted nature of the list for these attributes. The program traverses the linked list, comparing each node's attribute with the search key, and displays all matching books.

Implementation Details

The core of the application involves defining a BookNode class or struct, functions for file operations, linked list management (insertion, deletion, traversal), sorting, and searching algorithms. The main menu loop allows the user to select operations, ensuring the system is interactive and flexible. Error handling and input validation are vital to prevent invalid data entries or crashes.

Conclusion

This project combines fundamental data structures with sorting and searching algorithms to create a simple yet powerful library management system. Efficient data handling via linked lists and algorithms ensures scalability and performance, enabling library staff to manage their extensive collection smoothly. Strict adherence to original work and implementation in C++ within Visual Studio 2017/2019 ensures compatibility and best practices in software development.
