拥护根据系统界面的提示信息对图书馆信息进行查询、初始化等操作系统功能需求分析描述如下：（1）查询图书：根据图书编号进行查询，读者可以浏览或查询相关图书。

（2）系统主菜单：若未找到相应的书籍返回到上一级目录。

（3）图书登记：读者输入要查询的编号、出版社、作者姓名等信息，系统将进行处理。

（4）初始化：输入书号、书名、书籍的数量以空格隔开，建立新文件写入数据否则初始化失败。

（5）新书入库：可读入新书名称、编号、数量以空格隔开看是否有此类书籍。

（6）借书菜单：可输入读者编号和所借书编号或调用借书函数执行借书功能。

（7）还书菜单：可输入读者编号和所还书的编号执行还书功能，还书后修改图书库存量。

（8）保存连接数据：方便读者了解图书登记的相关信息，为图书管理人员和读者带来便利。

2.总体设计下面从系统的整体流程的功能模块系统界面及数据结构进行总体设计。

(1)总体思想本系统主要设计思想是实现图书馆的功能机管理系统信息的查询、初始化、添加新书、借书、还书等主要功能。

图书登记管理情况以文件的形式储存，系统的人机接口系用简单的字符界面进行交互，系统的设计方法是结构化实际方法，系统用C语言进行开发用户可以清晰的了解图书馆内的情况。

（2）系统模块结构图根据需求分析结果，图书登记管理系统可以分为三大模块：查询图书模块、图书登记管理模块、系统控制平台。

系统模块结构如图:3、概要设计㈠系统主菜单。

显示系统的主菜单，里面有相应的功能代码，根据选择各功能代码进入不同的界面。

功能主要包括：退出系统、查询图书、借书、还书、新书入库。

㈡查询图书信息进入此菜单功能模块，输入您要查询的图书的编号、名称、作者、出版日期等。

图书查询模块流程如图:㈢图书登记管理模块根据功能选择进行操作，主要包括建立图书入库文件的保存与修改，借书、还书文件的建立与修改。

对系统进行初始化。

4、数据结构设计图书信息和读者信息的数据结构系统云运用结构体来存放图书的编号、作者、出版、借书、还书、新书入库，读者的编号、姓名、借书名称等信息。

下面是结构体的简单描述：typedef struct bk{char book_num[11];char book_name[41];int book_kc;int book_xc;struct bk * next;}book;typedef struct rd{char reader_num[11];char reader_name[11];char reader_book_num[11];struct rd * next ;}reader;5、系统流程描述系统进行初始化后，根据提示输入图书、读者的相关信息后系统进入了主菜单，根据选择相应的功能代码进入不同的功能菜单。

主要包括退出系统、新书入库、图书查询、借书、还书、输出所有信息功能。

选择代码按回车键即可进入，进入功能模块后出现了不同选象，下面以进入借宿书模块为例：进入借书模块后系统将提醒选择1可返回主菜单，选择2可正式进入借书系统。

选择2后，系统提示“请输入所借书的相关信息，读者的相关信息。

6、界面设计一、系统主菜单void M_Form(){ char ch;printf("\nThe main window of books manage ");printf("\n 0:Exit");printf("\n 1:New book instore");printf("\n 2:Book check");printf("\n 3:Borrow book check in");printf("\n 4:Return book check in");printf("\n 5:Out put all information");do{printf("\n\n Please chose the code：");scanf("%c",&ch);fflush(stdin);}while(ch!='0'&&ch!='1'&&ch!='2'&&ch!='3'&&ch!='4'&&ch!='5');switch(ch){ case'0':exit(0);case'1':Form_Insert_New_Book();break;case'2':Form_Find_Book();break;case'3':Form_Borrow_Book();break;case'4':Form_Return_Book();break;case'5':load_data();print_book(h_book);print_reader(h_reader);M_Form();
