## 项目简介
|
|
|
|
|
|
|
|
|
|
本系统是自建设计项目,实现了图书管理中的借书和还书,查询书籍,以及书籍的添加、删除和显示所有书籍等功能。项目采用 C/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。

## 关于图书管理系统
|
|
|
|
|
设计一个图书管理系统,要求采用命令行菜单界面进行交互,具备查书、借书、还书、打印书籍 、添加、删除等基本功能,能够以表格和图表形式展示数据,采用 CSV 格式保存数据。
|
|
|
|
|
|
|
|
|
|
\
|
|
|
|
|
系统的功能性需求:
|
|
|
|
|
- 数据的查书、借书、还书、打印书籍、添加、删除展示。
|
|
|
|
|
|
|
|
|
|
系统的非功能性需求:
|
|
|
|
|
- 菜单驱动的命令行交互界面。
|
|
|
|
|
|
|
|
|
|

# 概要设计
|
|
|
|
|
系统主要分为用户界面和数据处理两大模块。
|
|
|
|
|
|
|
|
|
|
用户界面模块包括系统初始化(init),显示菜单(display_menu),选择菜单命令
|
|
|
|
|
(make_choice)、确认(confirm)、退出(quit)等子模块。
|
|
|
|
|
数据处理模块包括 添加图书( DoAddBook ) 、查找图书( DoFindBook ) 、删除图书( DoDeleteBook ) 、打印所有图书( DoPrintBook ) 、归还图书( DoRepaidBook ) 、借用图书 ( DoBoorowBook ) 、修改图书( DoReviseBook ) 、排序图书( DoSortBook )等子模块。
|
|
|
|
|
|
|
|
|
|
其中查询、添加、修改和删除数据还会用到根据编号查询数据的方法(find)。
|
|
|
|
|
上述各模块通过主程序(main)进行调用,系统模块图如下。
|
|
|
|
|
各模块的主要功能如下:
|
|
|
