Project Description

The project is a simple file-based system for managing library records in C++. The system stores book records and visitor records using a variable-length-field and delimiter record approach in the following order:

First : book records order:

Id_Leangth Id Name_length Name Author_length Author Category_length Category|...

Second : visitor records order:

Id_Leangth Id Name_length Name Visit_Date_length Visit_Date Borrowed_Book_length Borrowed_Book|...

The Spaces is just for easy read, no spaces written in record.

Book Information

The Book class contains the following fields:

• Id_length is an integer representing the book's ID length
• Id is an integer representing the book's ID
• Name_length is an integer representing the book's name length
• Name is a string representing the book's name
• Author_length is an integer representing the book's author length
• Author is a string representing the book's author
• Category_length is an integer representing the book's Category length
• Category is a string representing the book's Category

Visitor Information

The Visitor class contains the following fields:

• Id_length is an integer representing the visitor's ID length
• Id is an integer representing the visitor's ID
• Name_length is an integer representing the visitor's name length
• Name is a string representing the visitor's name
• Visit_date_length is an integer representing the visitor's visit date length
• Visit_date is a string representing the visitor's visit date
• Borrowed_book_length is an integer representing the book's borrowed book length
• Borrowed_book is a string representing the book's borrowed book

The project provides several operations for managing book and visitor records, including adding a new record, updating an existing record by ID or name, deleting a record by ID or name, searching for records by ID or name, and displaying top 5 records.
