图书借阅管理系统146318237

1、1 设计目的数据结构课程主要介绍最常用的数据结构，阐明各种数据结构内在的逻辑关系，讨论其在计算机中的存储表示，以及在其上进行各种运算时的实现算法，并对算法的效率进行简单的分析和讨论。进行数据结构课程设计要达到以下目的：n 了解并掌握数据结构与算法的设计方法，具备初步的独立分析和设计能力；n 初步掌握软件开发过程的问题分析、系统设计、程序编码、测试等基本方法和技能；n 提高综合运用所学的理论知识和方法独立分析和解决问题的能力；训练用系统的观点和软件开发一般规范进行软件开发，培养软件工作者所应具备的科学的工作方法和作风。2. 设计内容和要求主要分为两大功能：(1) 图书管理(增加图书、查询图书、删

2、除图书、图书借阅、还书)； (2) 会员管理(增加会员、查询会员、删除会员、借书信息)。设计要求：(1) 符合课题要求，实现相应功能；(2) 要求界面友好美观，操作方便易行；(3) 注意程序的实用性、安全性；3本设计所采用的数据结构采用两条单链表，其头结点分别为head、mhead的全局变量来存储图书信息和会员信息。其定义数据结构如下：/*图书信息结构体*/typedef struct elemchar bookid5;char bookname50;char bookauthor20;char bookmark2;char memberid4;elemtype;/*图书链表结点结构体*/ty

4、查询会员借书信息删除会员4.1 详细设计思想系统启动时，通过读取文件完成对以head、mhead为表头的单链表完成初始化。初始化后系统进入系统菜单，其运行界面如下：当选择功能1时，进入图书管理模块，其运行界面如下：当选择功能2时，进入会员管理模块，其运行界面如下：在图书管理界面中，当选择功能1时，查看所有图书，其运行界面如图：在会员管理界面中，当选择功能1时，查看所有会员，其运行界面如图：4.2各个实现函数为了实现上述功能，特定义以下函数原型,具体代码参见源代码部分：void main() /*入口*/void initallinfo() /*初始化图书和会员链表*/void welform(
