Library Management System in C++

Problem Statement:

This project implements a Library Management System using C++ and Object-Oriented Programming concepts. The system is designed to work on the Command Line Interface (CLI) and manages library operations for three types of users: Professors, Students, and Librarians. Each user type has distinct roles and permissions as described below.

Functionalities:

1. User Roles:

• Professor:

  • Can view all books in the library.
  • Can check if a book is available for issue.
  • Can issue an unlimited number of books for a duration of 60 days.
  • Late returns incur a fine of 5 rupees/day after the due date.

• Student:

  • Can view all books in the library.
  • Can check if a book is available for issue.
  • Can issue up to 5 books for a maximum of 30 days.
  • Late returns incur a fine of 2 rupees/day after the due date.

• Librarian:

  • Can add, update, and delete book records.
  • Can add, update, and delete user records.
  • Can view a list of all books and users.
  • Can track which books are issued to which users.

2. Login/Logout System:

• The system allows users to log in using credentials stored in a CSV file. Upon login, users can access functionalities specific to their role.

Implementation Details:

CSV Files:

• =users_data.csv: Stores details of users in the format [name, id, password, type of user], where:

  • type of user = 1 for Students.
  • type of user = 2 for Professors.
  • type of user = 3 for Librarians.

• books_data.csv: Stores details of books in the library in the format [name of book, author, publisher, ISBN code, is_issued], where is_issued is 1 if the book is issued and 0 otherwise.

• issued_books_data.csv: Stores records of issued books in the format [user id, name of book, ISBN code, timestamp]. The timestamp helps in calculating fines for overdue books.

Running the System:

1. Compile the program using:

   g++ main.cpp -o main
