This article mainly introduces the relevant knowledge of "how to write the code for C++ to implement the library management system". The editor shows you the operation process through an actual case, and the operation method is simple, fast and practical. I hope this article "how to write the code for C++ to implement the library management system" can help you solve the problem.

General thought

To develop the library management system with C++, it is necessary to set up class for students and books respectively, and call the methods in class to realize the operations such as students logging in to borrow books, returning books, and librarians to view information.
