四.总结
1.数据结构上：选用邻接矩阵，链式前向星，存图，然后建立结构体数组储存景点编号，名称，介绍
2.选项功能：可通过多个if语句实现，额外判断输入错误情况，还要实现连续输入错误情况下依旧可跳至功能
3.计算两点之间最短路径：选用链式前向星存图结构，Dijkstra算法，
用数组dis记录起点到每个结点的最短路径，
//bool 数组vis表示是否来过，dis[s]=0,其余为2的31次方-1，
//定义pos变量代表现在的位置,vis[pos]=true表示来过，初始值为起点
//枚举所有与pos相连的点：更新dis[i]按照：dis[i]=min(dis[i],dis[pos]+w)
//枚举所有未被标记的点，找到dis最小的点赋值给pos，vis[pos]==true;
//所有点都访问过程序结束。此时，dis[i]代表从起点到i的最短路径4.计算两点之间的所有路径：选用邻接矩阵的存图方式，dfs深搜。即建立一个栈，将与之起点相连的入栈，深搜下去，遇到结果，输出，不断回溯深搜到所有路径
5.查询景点信息并推荐最优路径：推荐最优路径本来选用的是克鲁斯卡尔算法，但初始地图设计使部分景点最优路径会绕圈，于是选用邻接矩阵Floyed算法计算最短路径，只需在Floyed算法中设立二维数组nodes，记录两个景点之间的结点，在输出路径时，只要两个景点之间有结点，就递归将中间点作为终点继续打印路径和将中间点作为起点继续打印路径，遇见nodes[u][v]=-1或等于起点或等于终点就返回；
void floyed_print1(int u, int v) { //floyed算法
if (nodes[u][v].a == -1 || nodes[u][v].a == u || nodes[u][v].a == v)
return;
else {
floyed_print1(u, nodes[u][v].a); //将中间点作为终点继续打印路径
cout <<Map[nodes[u][v].a].num << Map[nodes[u][v].a].name << "---->";
floyed_print1(nodes[u][v].a,v); //将中间点作为起点继续打印路径
}
}6.查询多个景点最优路径：只需将景点编号储存，并按照从大到小排序，之后操作如5
7.管理员修改景点功能只需找到景点编号，将景点名称，介绍修改即可，增加景点功能只需将填写景点名称，介绍，将与各节点距离插入链式前向星和邻接矩阵中即可，删除景点操作，因为之前功能实现，没考虑到删除景点操作，一但增加此操作，便会改动全局，没有实现。
8.公告栏，退出界面，进入界面设计好封面即可，麻烦操作就是判断功能选项和输入数据是否合理
