For library management, this project can consider multiple departments –e.g. Computer, Electronics, and Architecture. These departments work simultaneously with the operations as the following. 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. You may also search a book according to different identifications. Some sample functions are: Using Code::Block C++ without add or delete choice, only below points 1-void searchbooks(void) 2-void issuebooks(void) 3-void viewbooks(void) 4- void issuerecord() – With this function, you can keep record of the student to whom the book has been issued. 5- End of program
