能帮忙看看具体原因吗?
还有，能解释一下之前的问题吗？
先谢过

我现在是一些细节问题，你给我一个程序参考也没什么用啊

void output(struct Ticket *head1)
{
       struct Ticket *q;//建立量表的函数
       printf("班次\t时间\t起始站\t终点站\t行车时间\t额定载量\t已订票人数\t状态\n");
       q=head1->next;
       while(q!=NULL)
       {
              printf("%s\t%02d:%02d\t%s\t%s\t%f\t%d\t%d\t%s\t",q->number,q->ft.hour,q->ft.minute,q->origin_station,q->last_station,q->last_time,q->max_number,q->sold_ticket,q->condition);
          
           if((syshour>q->ft.hour)||((syshour==q->ft.hour) &&(sysminute>q->ft.minute)))
             printf("已发出\n");
           else
             printf(" \n");
           q=q->next;
       } 
}

错误太多，自己再好好看看

这次能运行了，结果如下：


真的对不起，我的C是自学的，真的有好多问题不懂，麻烦你教教我

乱码是因为文件里没有condition的信息吧，不要condition即可。

删了p->condition后，界面是这样的

我发现运行后不能返回主界面，就对主函数做了点修改，不然录入后就结束程序也没用啊，所以现在录入后就又会出现选项，不至于不能用。。

我把程序复制过来，，，出现一些warning，缺少头文件，所以我不能调试。。
我也不会应用文件去处理程序。
不过我个人给你提几个建议不妨在程序里面多插入几个printf（“*”）之类的，看看程序卡在哪个位置了找到位置后把那个导致程序崩溃的变量输出，看看和你设想的是不是有出入。

我的可以通过编译啊，为什么你不可以？

我这边没有相应的头文件，，
要include的那两行。。
