Library Management System In C With Source Code
The Library Management System In C is develop in C programming language and creating in a console based, This Simple Library Management System Project In C you can perform functions such as add books, return books, issue books, delete record of books issued, view record of books issued, search for books, and more. File handling has been extensively used in this project for almost all functions. So, this project can definitely guide you to understand C mini projects in a better way.
A Library Management System C Program has six departments – Computer, Electrical, Civil, Electronics, Mechanical and Architecture. These departments work simultaneously with the operations mentioned above. You can add a book to the Civil section, delete a book from the Electrical section or view issued book details of the Mechanical department.
This system also includes a downloadable Library Management System C Project Source Code for free, just find the downloadable source code below and click to start downloading.
Watch the video here to see the full running Library management system in C source code.
To start creating a Library Management System In C, make sure that you have code blocks or any platform of c language installed in your computer.
Steps on how to create a Library Management System In C
