题目：（一）试设计一个航空客运定票系统。基本要求如下：
1、    每条航线所涉及的信息有：终点站名、航班号、飞机号、飞机周日（星期几）、乘员定额、余票量、订定票的客户名单（包括姓名、订票量、舱位等级1，2或3）以及等候替补的客户名单（包括姓名、所需数量）。
2、    系统能实现的操作和功能如下：
1）    查询航线：根据客户提出的终点站名输出如下信息：航班号、飞机号、星期几飞行，最近一天航班的日期和余票额；
2）    承办订票业务：根据客户提出的要求（航班号、订票数额）查询该航班票额情况，若有余票，则为客户办理订票手续，输出座位号；若已满员或余票少余订票额，则需重新询问客户要求。若需要，可登记排队候补；
3）    承办退票业务：根据客户提出的情况（日期、航班号），为客户办理退票手续，然后查询该航班是否有人排队候补，首先询问排在第一的客户，若所退票额能满足他的要求，则为他办理订票手续，否则依次询问其它排队候补的客户。
3、    实现提示：两个客户名单可分别由线性表和队列实现。为查找方便，已订票客户的线性表应按客户姓名有序，并且，为了插入和删除方便，应以链表作为存储结构。由于预约人数无法预计，队列也应以链表作为存储结构。
     创建链表，队列
     查找链表，队列插入，删除

输入第一组数据：
1001 beijing plane1 21 100 50
1002 shanghai plane2 22 100 40
1003 tianjin plane3 23 100 30
-1 guangzhou plane4 100 60
这个行的，接着输入第二组数据就有问题了：
1001 any 50 3
1002 black 60 2
然后就不能运行了
编译也没错误，到底哪里错了，求助，给个提示也好

我觉得你得学会调试，一步步跟进看看

createnohead2 () {
  ...
  scanf("%d", rank);    //这行有问题
  ...
}

大牛求教。。怎么分开调试啊。。。我也是写完了一并调试。。。百十来个错一个一个改。。。好蛋疼。。。
