图书管理系统
2023年4月 成员1:王昊 成员2:孙艺哲 成员3:张江楠 成员4:郭佳慧
项目简介
本系统是程序设计与问题求解课程设计项目,实现了库存零件 CSV 格式数据文件的读取和保存,以及数据的增删改查(CRUD)、排序和图表显示等功能。项目采用 C 语言编程实现,在 VS Code 集成开发环境(IDE)中用 GCC 进行编译。系统采用模块化设计,程序结构清晰,采用菜单驱动的命令行界面,操作便捷,能够用 CSV 格式读取和保存数据,通用性强,能够用图表展示数据,直观清楚。 下载地址:https://bdgit.educoder.net/mac76tib2/test.git 项目开发过程中采用 Kanban(看板)进行任务管理和分工协作,并使用 Git 对程序代码和文档进行版本管理。任务分工情况如下:

关于图书管理系统
建立一个图书馆管理系统,可以处理以下对象: (1)图书馆基本信息 (2)图书馆的书籍 (3)图书馆管理员 (4)读者信息
需求分析
(1)查询图书馆的总信息 (2)查询图书馆藏书信息 (3)存入新书 (4)旧书处理 (5)根据书名检索书刊信息 (6)查询读者的借阅信息 (7)查询读者信息 (8)读者借书 (9)读者还书 (10)文件保存 (11)从文件读取
C1:函数模块
1.函数原形:int main(); 2.功能:调用ShowMainMenu()函数,显示主界面
