一、实验概述
1.1 实验题目
图书管理基本业务模拟
1.2 基本要求
（1)书的登记内容包括书号、书名、著作者、现存量和库存量等；学生信息包括借书证号、借阅信息等；
（2)以书号建立索引表（线性表）以提高查找效率；
（3）主要功能如下：
采编入库：新购一种书，确定书号后，登记到图书帐目表中，如果表中已有，则只将库存量增加；
借阅：如果一种书的现存量大于0，则借出一本，登记借阅者的书号和归还期限，改变现存量；
归还：注销对借阅者的登记，改变该书的现存量。
（4）输出形式：
能按书号、书名、著作者查找库存的书籍信息
能按学生的借书证号显示学生信息和借阅信息
书籍入库
借书功能实现
还书功能实现
1.3 问题描述
图书管理一般包括图书采编、图书编目、图书查询及图书流通（借、还书）等基本业务。要求设计一个图书管理信息系统，用计算机模拟实现上述系统功能。
二、详细设计
2.1 数据结构的设计
2.1.1 图书信息的存入
ofstream fout("book.txt");
if (fout)
{
fout << data.size() << endl;
//book p;
for (int i = 0; i <(int)data.size(); i++)
{
fout << data[i].idnum << " " << data[i].name << " " << data[i].author << " " << data[i].price << " " << data[i].kind << " " << data[i].room << " " << data[i].sum << " " << data[i].nowsum << " " << data[i].BorrowCount << " " << data[i].ok << " " << data[i].appointment << " " << data[i].borrowdate << " " << data[i].returndate << " " << endl;
}
fout.close();
}
2.1.2 学生信息存入
ofstream fout("student.txt");
if (fout)
{
fout << data1.size() << endl;
//student p;
for (int i = 0; i <(int)data1.size(); i++)
{
fout << data1[i].id << " " << data1[i].name << " " << data1[i].borrowsum << " " << data1[i].number << " " << data1[i].borrowday;
for (int j = 0; j<10; j++)
{
fout << " " << data1[i].b[j];
}
fout << endl;
}
fout.close();
}
2.2 算法的设计思想及流程图
2.2.1 主要函数的功能说明
1、void AddBook(book NewBook); //增加图书
2、void DeleteBook(string bookname, string author);//删除图书
3、void BorrowBook(string name, string author);//借阅图书
4、void BackBook(string name, string author, int k);//归还图书
5、void ShowAllBook(); //输出系统所有图书
6、void SearchBookPosWithname(string thebook); //按书名查询
7、void SearchBookPosWithAuthor(string theauthor);//按作者查询
8、void SearchBookPosWithKind(string kind);//按种类查询
9、int SearchBookPosWithNum(int theNum);//按编号查询
10、void SortBook(int ca); //排序
11、void Save(); //存入图书馆文件
12、void Save1();//存入学生文件
13、void printbook(book a);//输出某本书的所有信息
14、void revisebook(string name, string author);//修改某本书的信息
15、int SerchStudent(int id);//查询某个读者
16、void AddStudent(student a);//增加一个读者
17、void PrintStudent(int kid);//输出读者信息
18、int GetStudent();//返回读者总数
2.3 模块结构及流程图
2.3.1 程序总流程图
如图1所示：
图1 系统总流程图
2.3.2 管理员的图书管理模块流程
管理员的图书管理模块流程。如图2所示。
图2 图书管理模块
2.3.3 图书查询模块
图书查询模块如图3所示。
图3 图书查询模块
三、主要程序分析
Library::AddBook(book NewBook){data.push_back(NewBook);}
添加图书函数并将新增图书放到链表最后一位
Library::AddStudent(student newstudent){data1.push_back(newstudent);}
添加读者函数并将新增读者放到链表最后一位
Library::DeleteBook(string bookname, string author){
int pos = SearchBookPosWithAB(author, bookname);
if (pos != -1){data.erase(data.begin() + pos);return;}
删除函数：删除图书信息
Library::SearchBookPosWithname(string thebook){
int flag = 0;for (int i = 0; i <(int)data.size(); i++){
if (data[i].name == thebook){printbook(data[i]);flag = 1;}}
查询函数：所有查询方式匀与此类似，均为按值查找
Library::revisebook(string name, string author) if (data[i].author == author&&data[i].name == name){k = i;break;}
修改函数：对已存图书信息进行修改
四、程序运行结果
4.1 读者界面与管理员界面
4.2 显示所有图书信息界面
4.3 图书借阅界面
