C Program to Library Management Project with Full Source Code For Beginners

Library Management using C Program.

Introduction:

  • The mini-project ‘Library Management’ is the sample project for managing a library.
  • The project aims at developing a library management system using the C language that enables an organization to maintain its library.
  • The project demonstrates the creation of a user interface of a system, without the use of the C Graphics library.
  • The application uses the basic C function to generate menus, show message boxes and print text on the screen.
  • To display customized text with colors and fonts according to application requirements, functions have been created in the application, which fetches the exact video memory addresses of a target location, to write text at a particular location.
  • The application also implements the concept of structures to define the library items.
  • It also effectively applies the various C concepts such as file operations, looping and branching constructs and string manipulation functions.
