图书借阅管理系统数据结构课程设计说明书

1、中北大学数据结构课 程 设 计 说 明 书   学生姓名:周西财 学 号：0706054236 学 院:电子与计算机科学技术学院专 业:软件工程 题 目:图书借阅管理系统成绩 指导教师周海英  2009 年 6 月 24 日1 设计目的通过设计掌握数据结构课程 中学到的基本理论和算法并综合运用于理论实际问题中,它是理论与实践结合的重要过程.设计要求学会对实际问题定义相关数据结构,并采用恰当的设计方法和算法解决问题,同时训练学生进行复杂程序设计的技能和培养良好的程序设计习惯.人工管理图书的手续繁索、效率低下

2、给具有强烈时间观念的管理人员带来了诸多不便，学校图书馆缺少一套完善的图书管理软件，为了对图书的管理方便，因此必须开发图书管理系统。2. 设计内容和要求内容：1)图书管理(增加图书、查询图书、删除图书、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)；要求：根据设计内容建立相关数据的动态链表存储结构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 bookauthor

3、20;char bookmark2;char memberid4;elemtype;/*图书链表结点结构体*/typedef struct nodeelemtype data;struct node *next;lnode,*linknode;/*会员信息结构体*/typedef struct memberelemchar memberid4;char membername20;memberelemtype;/*会员链表结点结构体*/typedef struct membernodememberelemtype data;struct membernode *next;mlnode,*mlin

4、knode;4功能模块详细设计图书借阅管理系统图书管理模块会员管理模块增加图书查询图书删除图书图书借阅还书增加会员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： 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() /*系统总菜单*/voi

6、*增加会员模块*/void selectmember() /*按编号查询会员*/void deletemember() /*按编号删除会员*/void membermanagetitle() /*会员管理二级菜单*/void membermanage() /*二级会员管理功能选择函数*/程序调试运用数据如下：图书初始数据表bookidbooknamebookauthorbookmarkmemberid0001sanguoyanyiluoguanzhongN00002hongloumengcaoxueqinN00003xiyoujiwuchengenY0010004shuihuzhuanshin
