原创c语言图书馆管理系统源代码

原创C语言图书馆管理系统源代码介绍图书馆作为一个重要的知识储备和学习场所，必须进行有效的管理和组织。

使用C语言编写的图书馆管理系统可以帮助图书馆实现自动化的借阅、归还和管理功能。

本文将介绍一个原创的C语言图书馆管理系统的源代码。

功能概述这个图书馆管理系统具有以下核心功能： - 图书管理：包括添加图书、删除图书、查询图书等操作。

- 借阅管理：可以进行借阅操作，记录借阅者和借阅时间。

- 归还管理：可以进行归还操作，并更新图书的可借状态。

- 用户管理：管理借阅者的信息，包括添加用户、删除用户、查询用户等操作。

数据结构设计该图书馆管理系统使用了以下几种数据结构： 1. 图书（Book）结构体：包含图书的ID、书名、作者、可借状态等字段。

2. 用户（User）结构体：包含用户的ID、姓名、地址等字段。

3. 借阅记录（BorrowRecord）结构体：包含借阅者ID、图书ID、借阅时间等字段。

系统流程整个系统的流程可以分为以下几个步骤： 1. 用户打开系统，进入主菜单。

2. 用户选择不同的功能选项（如图书管理、借阅管理、用户管理等）。

3. 根据用户选择的功能，进入相应的功能界面。

4. 用户可以根据提示，输入相应的信息进行图书管理、借阅管理或用户管理操作。

5. 用户完成操作后，可以选择返回主菜单或退出系统。

代码实现以下是一个简化版的C语言图书馆管理系统的源代码：```c #include <stdio.h>// 定义结构体 struct Book { int id; char name[50]; char author[50]; int isAvailable; };struct User { int id; char name[50]; char address[100]; };struct BorrowRecord { int userId; int bookId; char borrowDate[20]; };// 函数声明 void addBook(); void deleteBook(); void searchBook(); void borrowBook(); void returnBook(); void addUser(); void deleteUser(); void searchUser();int main() { int choice;do {// 显示主菜单printf(\。
