注：全代码由博主个人耗时两个星期开发，实现了基础的公交管理系统功能：1.前端用户查询站点以及查看所有站点。2.后端管理员权限，实现登录系统检验，添加路线以及删除路线。最重要的是使用EasyX实现了星穹轨道的启动以及抽卡界面以及音效。
注意：代码可以直接拿，但是可视化部分的素材需收费（博主做可视化部分就做了一个多星期），需要的可以直接看文章结尾。
话不多说直接上代码：
#define _CRT_SECURE_NO_WARNINGS
/*开发日志
* 1.明确公交管理系统分为后台和前台
* 2.前台的主要功能是给用户规划最佳路线
* 3.后台的主要功能是给管理员添加和删除路线使用
* 使用技术：
* 1.数据处理
* 1.1去重以及划分路线范围（路线范围后加）
* 1.2给每个站点进行编号便于处理
* 2.进行图的建立
* 3.使用Dijkstra算法给出最短路径
*
* 日志12-21 准备可视化开发
* 基本核心算法已经就绪
* 12-25开场动画准备完毕，开始进入第二阶段，查询功能判定
* 判断写好了接下来就是最后的输出了
* 遇到困难了，发现无法读取中文
* 好的困难解决将整个程序改为了unioncode字符集完成开发
* 又遇到难点了，怎么在文本框里换行输入啊,算了直接多设置几个控件就好了
* 好的管理员权限开发完毕
* 1-1开始开发使用者权限
* 1-2上午完成查询站点开发，使用了string转为wchar_t*的技术
*
*
* 与1-2晚上完成开发，完美收工！！！！！！

接下来讲解一下大概的算法思想（不想看的可以跳过）:
1.首先是文件的读取和写入
文件读取这一方法在这个程序中占有不可取代的地位，首先需要知道c++中的文件读取方式，ifstream是读取流，fstream是输入流，具体的使用方法可以去网上搜索，这边介绍两种最简单的使用方法
以下是写入方式，该写入方法会覆盖原本的文件，相当于从头开始写入，并不建议
fstream fin; //写入格式
fin.open("路线信息.txt", ios::out);该方法属于写入方法的追加写入，也是比较常用的方法
fstream fin; //写入格式
fin.open("路线信息.txt", ios::out | ios::app);以下是读取方式，比较简单
ifstream ReadFile;
ReadFile.open("路线信息.txt", ios::in);//ios::in 表示以只读的方式读取文件2.初始化图
文章中的初始化函数包括初始化数据以及创建图
//初始化
void init() {G.sum = CountLines();Road_Sum = CountRoads();ifstream fin;fin.open("站点信息.txt", ios::in);if (!fin){std::cerr << "cannot open the file";}for (int i = 0; i < G.sum; i++) {int a;string s;fin >> a >> s;m.insert(pair<string, int>(s, a));G.s[i].number = a;G.s[i].name = s;}fin.close();
}//创建图
void Creat_Graph() {ifstream fin;fin.open("路线信息.txt", ios::in);if (!fin){std::cerr << "cannot open the file";}for (int i = 0; i < Road_Sum; i++) {int sum = 0;Road r;r.sum = 0;fin >> r.name;string t;fin >> t;while (t.compare("end") != 0) {map<string, int>::iterator iter;iter = m.find(t);if (iter != m.end()) {r.zhandian[sum++] = iter->second;fin >> t;}}r.sum = sum;//结束之后直接开始点之间相连for (int j = 0; j < r.sum - 1; j++) {int a1 = r.zhandian[j];int a2 = r.zhandian[j + 1];situation* s1 = (situation*)malloc(sizeof(situation));situation* s2 = (situation*)malloc(sizeof(situation));s2->number = G.s[a2].number;s1->number = G.s[a1].number;s2->next = G.s[a1].firstnode;G.s[a1].firstnode = s2;s1->next = G.s[a2].firstnode;G.s[a2].firstnode = s1;}v.push_back(r); //将路线添加到容器里}fin.close();
}其实这些学过数据结构的同学应该都是会的，但是这边我要讲一下为什么这个项目中采取了邻接表的形式而不是邻接矩阵，我认为主要有以下两点考虑：
1.公交管理系统中的数据大概率是一个稀疏矩阵，如果使用矩阵的形式储存就会浪费很多空间。
2.在后续的添加和删除路线时，矩阵会直接切断两个站点之间的连接，可能导致其他路线无法正常进行，而使用邻接表时就会重复添加某个站点（这个站点存在于多条路线中），注意，重复添加站点并不会导致程序出现问题，相反，在删除站点时，由于站点多次创建，删除一个依旧会有该站点存在，就不会导致bug出现，这也是一个核心思想。
3.Dijkstra算法
整个算法由三个部分组成
bool next(int x, int y) { //为了判断这两个点是否相连situation* p;for (p = G.s[x].firstnode; p; p = p->next) {if (p->number == y)return true;}return false;
}int findmindist(int dist[], bool visit[]) { //找最小的路径int minv, v;int mindist = 999;for (v = 0; v < G.sum; v++) {if (visit[v] == false && dist[v] < mindist) {mindist = dist[v];minv = v;}}if (mindist < 999) {return minv;}elsereturn -1;//表示不存在
}void Dijkstra(int x, int dist[], int parent[], bool visit[]) //Dijkstra算法，传入源顶点
{int v, w;situation* m;//初始化for (int i = 0; i < G.sum; i++) {dist[i] = 999;parent[i] = -1;visit[i] = false;}for (m = G.s[x].firstnode; m; m = m->next) { //只找相邻点dist[m->number] = 1;parent[m->number] = x;}//先将起始点收入集合dist[x] = 0;visit[x] = true;while (findmindist(dist, visit) != -1) {v = findmindist(dist, visit);visit[v] = true;for (w = 0; w < G.sum; w++) {if (visit[w] == false && next(v, w) == true) {if (dist[w] > dist[v] + 1) {dist[w] = dist[v] + 1;parent[w] = v;}}}}
}以上是基于邻接表的迪杰斯特拉算法，函数结束后，dist中储存着源节点到每个节点的最短距离，这边不建议采用弗洛伊德算法大家懂得都懂。
4.找出需要经过的路线并打印
这部分算法是一个难点，你需要沿着某一条路线一直走，然后在某个点下车换成另一辆车，详细代码有点屎山，注释都写了有需要的小伙伴可以研究一下（忽略可视化部分）
void printmy(int x, int y, int parent[], int dist[]) {putimage(0, 0, &sucai7);string sresult=""; //用来可视化int x1 = 0;int y1 = 100;int s = 0;int nums[100];int k = 0;int t = y;//这里犯了个致命的错误，如果两个点之间没有相连就会一直死循环if (dist[t] == 999) {settextcolor(WHITE);settextstyle(50, 0, L"黑体");outtextxy(900, 500, L"不在已知路线中，请联系管理员");cout << "不在已知路线中，请联系管理员" << endl;return;}while (parent[y] != x) {nums[k++] = parent[y];y = parent[y];}sresult = sresult.append("从");sresult = sresult.append(G.s[x].name);sresult = sresult.append("到");sresult = sresult.append(G.s[t].name);sresult = sresult.append("需要");sresult = sresult.append(to_string(dist[t]));sresult = sresult.append("站");cout << "从" << G.s[x].name << "到" << G.s[t].name << "需要" << dist[t] << "站" << endl;settextcolor(WHITE);settextstyle(50, 0, L"黑体");outtextxy(0, 50, multiByteToWideChar(sresult));sresult = "";//这里我们做一个小小的改进，也就是我们希望得到啊具体的路线信息//也就是说两个以上相邻的站点才有可能是一路//我们开辟一个新的数组来储存线路过程//重要算法int result[100];result[0] = x;for (int i = 1; i <= k; i++) {result[i] = nums[k - i];}result[k + 1] = t;int towards = 0;//表示方向，0表示向后查找，1表示向前查找int i = 0;while (1) {for (int j = 0; j < v.size(); j++) { //线路容器int m = 0; //开关int num = 0;//先要找到首个站点的所在容器int n = 0;//这里注意如果从开头查找就要进行第二次判断while (n < v[j].sum) {if (v[j].zhandian[n] == result[i] && i == 0) { //先找到首个站点在容器中的位置ni++;num++;m = 2;break;}//就是上一次路线断了之后查找第一个站点位置,他又可能往回坐车，所以或着也需要判断else if (v[j].zhandian[n - 1] == result[i - 1] && n > 0 && v[j].zhandian[n] == result[i] && i > 0) {cout << "乘坐" << v[j].name << " " << G.s[result[i - 1]].name << "->" << G.s[result[i]].name;sresult = sresult.append("乘坐");sresult = sresult.append(v[j].name);sresult = sresult.append(" ");sresult = sresult.append(G.s[result[i - 1]].name);sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);i++;num = num + 2;m = 1;break;}else if (v[j].zhandian[n - 1] == result[i] && n > 0 && v[j].zhandian[n] == result[i - 1] && i > 0) {cout << "乘坐" << v[j].name << " " << G.s[result[i - 1]].name << "->" << G.s[result[i]].name;sresult = sresult.append("乘坐");sresult = sresult.append(v[j].name);sresult = sresult.append(" ");sresult = sresult.append(G.s[result[i - 1]].name);sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);i++;n--;num = num + 2;m = 1;break;}else {n++;}}if (n >= v[j].sum)continue;//这里之所有不n++是因为可能是往前找的if (result[i] == v[j].zhandian[n + 1] && m == 1) {n++;cout << "->" << G.s[result[i]].name;sresult=sresult.append("->");sresult=sresult.append(G.s[result[i]].name);towards = 0;num++;i++;n++;while (n < v[j].sum) {if (result[i] == v[j].zhandian[n]) {cout << "->" << G.s[result[i]].name;sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);n++;i++;num++;}else {break;}}}else if (result[i] == v[j].zhandian[n + 1] && m == 2) {n++;cout << "乘坐" << v[j].name << " " << G.s[result[i - 1]].name << "->" << G.s[result[i]].name;sresult = sresult.append("乘坐");sresult = sresult.append(v[j].name);sresult = sresult.append(" ");sresult = sresult.append(G.s[result[i - 1]].name);sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);towards = 0;num++;i++;n++;while (n < v[j].sum) {if (result[i] == v[j].zhandian[n]) {cout << "->" << G.s[result[i]].name;sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);n++;i++;num++;}else {break;}}}//向前查找if (v[j].zhandian[n - 1] == result[i] && m == 1) {n--;cout << "->" << G.s[result[i]].name;sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);towards = 1;num++;i++;n--;while (n < v[j].sum && n >= 0) {if (result[i] == v[j].zhandian[n]) {cout << "->" << G.s[result[i]].name;sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);n--;i++;num++;}else {break;}}}else if (v[j].zhandian[n - 1] == result[i] && m == 2) {n--;cout << "乘坐" << v[j].name << " " << G.s[result[i - 1]].name << "->" << G.s[result[i]].name;sresult = sresult.append("乘坐");sresult = sresult.append(v[j].name);sresult = sresult.append(" ");sresult = sresult.append(G.s[result[i - 1]].name);sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);towards = 1;num++;i++;n--;while (n < v[j].sum && n >= 0) {if (result[i] == v[j].zhandian[n]) {cout << "->" << G.s[result[i]].name;sresult = sresult.append("->");sresult = sresult.append(G.s[result[i]].name);n--;i++;num++;}else {break;}}}if (num >= 2) {settextcolor(WHITE);settextstyle(30, 0, L"黑体");cout << endl;if (10 + y1 * s >= 950) {x1 = x1 + 600;s = 0;}outtextxy(x1,200+ y1 * s, multiByteToWideChar(sresult));s++;sresult = ""; //一次路线结束清空break;}}if (i > k + 1) {break;}}
}5.添加删除路线
这个部分是最简单的没有什么特别好说的，就是找到对应的站点，然后删除或者添加即可。
//添加路线
//这边有一个点我们需要知道已有的站点中是否存在该站点
//如果有就不做操作
//如果没有就需要写入新的站点
//对于我们所使用的算法即使重复添加路线也并不会产生影响
//在读取的同时还要进行追加写入

这边需要特别提示：在我们删除文件中的某一段时，由于没有直接的方法删除，我们需要设置一个中间文本，从原文本中一直读取到需要删除部分的内容然后跳过这段内容，将其他部分的内容都存入这个中间文本中，然后清空原文本，最后将中间文本中的内容再重新输入到原文本中即可，注意中间文本在使用完毕之后需要清空。
//首先我们要明确，在删除路线的时候站点不需要发生改变
//我们这里的需求是删除某一条线路，线路名字已知
//这里就体现出了重复建立节点的好处，即使删除了两点之间的节点也不会导致其他有相同节点的路线发生变化

}最后提一点小小的建议：
1.我们需要在学习完一门语言之后进行一定简易项目的实战有利于我们巩固该语言的使用。
2.你在开发一个全新的项目过程中可能会困难重重，就像博主在开发可视化部分的时候经理了3，4次的代码大改（一般来说这是大忌）,同时也遇到了许多不可抗拒的困难，由于没有人的帮助，博主只能靠自身的水平和网上搜来的结果一步一步试验，还有就是上一个项目的经验，大家可以看我的上一个项目c语言仿天天酷跑小游戏
如果代码写的烂不要喷我，额算了想喷就喷吧，希望大家指出我的不足
