校园导航系统源代码

数据结构-校园导航系统简介:本系统采用C语言编写,运行环境为Dev-C++;容以电子科技大学南校区为例;主要功能有:1.查询景点信息;2.查询两景点间最短距离;3.查询两景点间所有路线;4.查询西电校园地图;5.修改景点和路径信息.注意事项:在进行修改景点和路径信息操作前,请在可执行文件目录下用记事本创建”superUser.CODE”文件来存放用户名与密码(中间以空格隔开),否则无法进入.源代码:#include <string.h>#include <stdio.h>#include <conio.h>#include <stdlib.h>#include <ctype.h>#define Max 20000typedef struct ArcCell{int adj; //两个景点间的距离}ArcCell;typedef struct VertexType{int number; //景点编号char sight[100]; //景点名称char description[1000]; //景点简介char particular1[1000];char particular2[1000];char particular3[1000]; //景点详情}VertexType;typedef struct{VertexType vex[20]; //最多存放20个景点信息ArcCell arcs[20][20]; //两个景点间的距离int vexnum,arcnum;}MGraph;MGraph G;char nameofschool[100]; //学校名称int NUM=9;int P[20][20];int p[20];int visited[20];int a=0;long int D[20];int x[20]={0};//函数声明void CreateUDN(int v,int a);void narrate();void ShortestPath(int num);void output(int sight1,int sight2);char Menu();void search();char SearchMenu();void HaMiTonian(int);void Searchpath1(MGraph g);void disppath(MGraph g,int i,int j);void path(MGraph g,int i,int j,int k);void NextValue(int);void display();int Addnewsight(int n);int Deletesight(int n);void Changesight();char Changemenu();char Sightmenu();int Maintain(void);int VerificatianIdentity(void);void map();//主函数int main(){int v0,v1;int MaintainFlag;char ck;system("color 0F");CreateUDN(NUM,11);do{ck=Menu();switch(ck){case '1':search();break;case '2':system("cls");narrate();printf("\n\n\t\t\t请选择起点景点（0～%d）：",NUM-1);scanf("%d",&v0);printf("\t\t\t请选择终点景点（0～%d）：",NUM-1);scanf("%d",&v1);ShortestPath(v0);output(v0,v1);printf("\n\n\t\t\t\t请按任意键继续...\n");getchar();getchar();break;case'3':system("cls");narrate();x[0]=1;Searchpath1(G);printf("\n\n\t\t\t\t请按任意键继续...\n");getchar();getchar();break;case'4':system("cls");map();printf("\n\n\t\t\t\t\t请按任意键继续...\n");getchar();getchar();break;case'5':system("cls");narrate();MaintainFlag = Maintain();switch(MaintainFlag){case'1':system("cls");narrate();NUM=Addnewsight(NUM);system("cls");narrate();break;case'2':NUM=Deletesight(NUM);break;case'3':Changesight();break;}break;};}while(ck!='e');return 0;}//主菜单char Menu(){char c;int flag;do{flag=1;system("cls");narrate();printf("\n\t\t\t┏━━━━━━━━━━━━━━━┑\n"); printf("\t\t\t┃┃\n");printf("\t\t\t┃1、查询景点信息┃\n");printf("\t\t\t┃2、查询两景点间最短路径┃\n");printf("\t\t\t┃3、查询两景点间所有路线┃\n");printf("\t\t\t┃4、查看西电校园地图┃\n");printf("\t\t\t┃5、修改景点和路径信息┃\n");printf("\t\t\t┃e、退出┃\n"); printf("\t\t\t┃┃\n");printf("\t\t\t┗━━━━━━━━━━━━━━━┛\n");printf("\t\t\t\t请输入您的选择：");scanf("%c",&c);if(c=='1'||c=='2'||c=='3'||c=='4'||c=='5'||c=='e')flag=0;}while(flag);return c;}//查询菜单char SearchMenu(){char c;int flag;do{flag=1;system("cls");narrate();printf("\n\t\t\t┏━━━━━━━━━━━━━━━┑\n"); printf("\t\t\t┃┃\n");printf("\t\t\t┃1、按照景点编号查询┃\n");printf("\t\t\t┃2、按照景点名称查询┃\n");printf("\t\t\t┃e、返回┃\n"); printf("\t\t\t┃┃\n");printf("\t\t\t┗━━━━━━━━━━━━━━━┛\n");printf("\t\t\t\t请输入您的选择：");scanf("%c",&c);if(c=='1'||c=='2'||c=='e')flag=0;}while(flag);return c;}//查询信息void search(){int num;int i;char c;char name[20];do{system("cls");c=SearchMenu();switch (c){case '1':system("cls");narrate();printf("\n\n\t\t请输入您要查找的景点编号：");scanf("%d",&num);for(i=0;i<NUM;i++){if(num==G.vex[i].number){printf("\n\t\t您要查找景点信息如下:");printf("\n\t\t(%d)%-5s:%-25s\n\n",i,G.vex[i].sight,G.vex[i].description);printf("\t\t\t\t\t详情介绍:\n\t\t%-s\n",G.vex[i].particular1);printf("\t\t%-s\n",G.vex[i].particular2);printf("\t\t%-s\n",G.vex[i].particular3);printf("\n\t\t按任意键返回...");getchar();getchar();break;}}if(i==NUM){printf("\n\n\t\t\t没有找到！");printf("\n\n\t\t\t按任意键返回...");getchar();getchar();}break;case '2':system("cls");narrate();printf("\n\n\t\t请输入您要查找的景点名称：");scanf("%s",name);for(i=0;i<NUM;i++){if(!strcmp(name,G.vex[i].sight)){printf("\n\t\t您要查找景点信息如下:");printf("\n\t\t(%d)%-5s:%-25s\n\n",i,G.vex[i].sight,G.vex[i].description);printf("\t\t\t\t\t详情介绍:\n\t\t%-s\n",G.vex[i].particular1);printf("\t\t%-s\n",G.vex[i].particular2);printf("\t\t%-s\n",G.vex[i].particular3);printf("\n\t\t按任意键返回...");getchar();getchar();break;}}if(i==NUM){printf("\n\n\t\t\t没有找到！");printf("\n\n\t\t\t按任意键返回...");getchar();getchar();}break;}}while(c!='e');}//构造图形void CreateUDN(int v,int a) {int i,j;strcpy(nameofschool,"电子科技大学");G.vexnum=v;G.arcnum=a;for(i=0;i<20;++i) G.vex[i].number=i;strcpy(G.vex[0].sight,"东门");strcpy(G.vex[0].description,"学校正门,可乘坐公交车,出租车等交通工具.
