C++ Program and Project to implement Library Management System

C++ Program and Project to Implement Library management system is the system in which we can provided a best service for public in library field. Basically we used manually system in a lots of field. But now a days we should increase our service speed. So that we serve everyone who is needy. The library management system works for reducing overload of librarian. We can easily search the book and issued the book. All data can be easily managed in this system.

This project of “ LIBRARY MANAGEMENT SYSTEM ” of gives us the complete information about the library. We can enter the record of new books and retrieve the details of books available in the library. We can issue the books to the students and maintain their records and can also check how many books are issued and stock available in the library. In this project we can maintain the late fine of students who returns the issued books after the due date.

The Library Management System is designed & developed for a receipt and issuance of books in the library along with the student’s details. The books received in the library are entered in Books Entry form and the new student is entered in the student entry form. When the student wants to get the desired book the same is issued on the availability basis to the student. The issuance and due date for the returning of the book is also entered into the Book Issue form under third menu Book Issue. The student has to pay the fine if any on the basis of no. of days delayed deposit of the book in the library.
