试了一下每个模块都中断T_T，搞半天不知道为什么。。。。感觉思维定死了。。。。大家有什么建议或者帮忙看出问题的欢迎指出来，肯定虚心接受身体力行

上面是所有的代码，下面是自己遇到的一些问题，

void insert_flight(fly *P, char *plane_num, char *city1, char *city2, char *time1, char *time2, int plane_room, float price, float zhekou, int sit)

 {
      fly *q;
      q = (fly*)malloc(sizeof(fly));
      strcpy_s(q->plane_num, plane_num);
      strcpy_s(q->city1, city1);
      strcpy_s(q->city2, city2);
      strcpy_s(q->time1, time1);
      strcpy_s(q->time2, time2);
      q->plane_room = plane_room;
      q->price = price;
      q->zhekou = zhekou;
      q->sit = sit;
      q->next = NULL;
      P->next = q;
      P = P->next;

 }

这个是插入数据操作，目的是在链表尾插入，可是不知道为什么只能输入一组数据，第二组输进去立马取代了第一组的数据T_T.

void creat_fly(fly *P)

 {
      fly *p;
      p=P;
      char plane_num[10], city1[20], city2[20], time1[20], time2[20];
      int plane_room, sit, mark = 1;
      float price, zhekou;
      if (p != NULL)
          p = p->next;
      while (mark == 1)
      {
          printf("请输入航班号：");
          scanf_s("%s", plane_num, sizeof(plane_num));
          printf("请输入出发地：");
          scanf_s("%s",city1,sizeof(city1));
          printf("请输入终点站：");
          scanf_s("%s", city2, sizeof(city2));
          printf("请输入起飞时间：");
          scanf_s("%s",time1,sizeof(time1));
          printf("请输入抵达时间：");
          scanf_s("%s",time2,sizeof(time2));
          printf("请输入票价：");
          scanf_s("%f",&price);
          printf("请输入折扣：");
          scanf_s("%f",&zhekou);
          printf("请输入座位数：");
          scanf_s("%d",&plane_room);
          printf("请输入是否满仓（0表示未满，1表示满仓）："); 
          scanf_s("%d",&sit);
          insert_flight(p, plane_num, city1, city2, time1, time2, plane_room, price, zhekou, sit);
          printf("增加航班成功！\n");
          printf("是否继续增加航班（1表示继续，0表示停止）：");
          scanf_s("%d", &mark);

      strcpy_s(q->time1, time1);
      strcpy_s(q->time2, time2);
      q->plane_room = plane_room;
      q->price = price;
      q->zhekou = zhekou;
      q->sit = sit;
      q->next = NULL;
      P->next = q;
      P = P->next;

为什么我报这个呢

我这个使用vs2013写的，scanf strcpy要求_s

我说的分模块调试就是  比如你有5个主菜单  每个主菜单下又设置了3个子菜单  那么你有15个子模块

你要逐一调试这15个模块 而不是把15个模块都写完了一起调试  

你比如 录入信息 模块 那你针对的代码就是录入信息这一部分，把这一部分弄到怎么测试都没有bug 之后 在去研究 什么修改 啊 查询啥的

单个模块怎么调试啊？可以举个例子么。。。。。有图示过程没。。。一直都是全部写完才搞的

简单点  你把所有代码都弄一份copy  然后再把现在的代码 涉及其他模块的都删除   把相关的菜单接口都关闭（删除或者注释掉）

调试好之后  再把相关的代码逐一的copy回来 直至所有模块全部通过测试

没有主函数也可以调试bug么？我写的时候是这样的，比如说写完初始化的部分了，然后就点那个“本地windows调试器”，他没报错我就继续了。。。。。难倒还可以直接看出自己这部分代码的效果？
