基于list容器的简单图书管理系统.doc

这是一个使用list容器的简单图书管理系统，可以实现对增删改查，借书还书操作。以下代码为VS2008 win32 控制台应用程序。#include stdafx.h#include #include #include #include using namespace std;class Bookpublic:int iBid;/图书ISBN编号char bName10;/图书名称int b_flag;/图书标志位，为在架，为借出Book(int,char na,int);void Setflag(list *,char *,int);bool Setflag(std:list *obv,char na10,int iflag)list:iterator it = (*obv).begin();while(it != (*obv).end()if(!strcmp(na,it-bName)Book book(it-iBid,it-bName,iflag);(*obv).erase(it);(*obv).push_back(book);return true;it+;Book:Book(int id,char name,int i)iBid = id;strcpy(bName,name);b_flag = i;list * Addbooks(list *obv)coutid;coutname;Book book(id,name,1);(*obv).push_back(book);return obv;void Showbooks(list obv)list:iterator it = obv.begin();if(obv.empty()cout库中没有书籍，请先添加书籍endl;elsecout所有书籍：endl;while(it != obv.end()if(*it).b_flag = 1)coutISBN: iBidtt书名: bNamett状态：在架endl;else if(*it).b_flag = 2)coutISBN: iBidtt书名: bNamett状态：已借出endl;it+;coutendl;list * Delbooks(list * obv)coutcBookname;list:iterator it = (*obv).begin();int bid = 0;while(it != (*obv).end()if(!strcmp(cBookname,it-bName)int bid = it-iBid;char cTempname10;strcpy(cTempname,it-bName);(*obv).erase(it);cout删除成功,删除的书ISBN为%dbid书名为：%scTempnameendl;break;it+;return obv;bool Findbooks(list * obv)list:iterator it = (*obv).begin();coutcBookname;while(it != (*obv).end()if(!strcmp(cBookname,it-bName)if(it-b_flag = 1)cout查找成功！查找到的书本信息为：ISBN：iBid书名：bName状态：在架b_flag = 2)cout查找成功！查找到的书本信息为：ISBN：iBid书名：bName状态：已借出endl;return true;it+;list * Borrowbooks(list *obv)coutcBookname;bool flag = Setflag(&(*obv),cBookname,2);if(flag)cout借书成功!endl;elsecout没有这本书或这本书没有库存了endl;return obv;list * Returnbooks(list * obv)coutcBookname;list:iterator it = (*obv).begin();while(it != (*obv).end()if(!strcmp(cBookname,it-bName)if(it-b_flag = 2)Setflag(&(*obv),cBookname,1);cout还书成功，欢迎下次光临endl;break;elsecout你未借过这本书endl;break;it+;return obv;void Savetofile(list * obv)list:iterator it = (*obv).begin();FILE * f1 = fopen(.data.txt,w);if(!f1)coutb_flag = 1)fprintf(f1,%dt%st在架n,it-iBid, it-bName);elsefprintf(f1,%dt%st已借出n,it-iBid,it-bName);it+;fclose(f1);class Bdatapublic:list obv;/list:iterator it;void Bookui()cout|-|endl;cout| 图书维护 |endl;cout| 1 增加 |endl;cout| 2 借书 |endl;cout| 3 还书 |endl;cout| 4 查找 |endl;cout| 5 删除 |endl;cout| 6 保存 |endl;cout| 7 显示 |endl;cout| 0 退出 |endl;cout|-|endl;list * Loadfile(list * obv)FILE * f1 = fopen(.data.txt,r);list:iterator it = (*obv).begin();int i;char na10;char flag10;while(1)int j = fscanf(f1,%dt%st%s,&i,na,flag);if(j = EOF)break;if(!strcmp(flag,在架)Book book(i,na,1);(*obv).push_back(book);else if(!strcmp(flag,已借出)Book book(i,na,2);(*obv).push_back(book);/it+;return obv;int _tmain(int argc, _TCHAR* argv)Bdata bdata;if(bdata.obv.empty()Loadfile(&bdata.obv);char in;doBookui();cinin;switch(in)case 1:Addbooks(&bdata.obv);break;case 2:Borrowbooks(&bdata.obv);break;case 3:Returnbooks(&bdata.obv);break;case 4:if(!Findbooks(&bdata.obv)cout查找失败，查找的书籍不存在endl;break;case 5:Delbooks(&bdata.obv);break;case 6:Savetofile(&bdata.obv);break;case 7:Showbooks(bdata.obv);break;c
