Question

二、航空订票系统
1．航班管理：每个航班信息包括航班号，飞机号，目的地，订票数，余票数等．假设现在有3条航线，目的地分别是上海、广州和武汉，每条航线上只有一架飞机，飞机上可乘坐100人(即初始订票数为0，余票数为100)，将所有飞机信息存入数组airline中．
2．订票业务
(1)客户信息包括姓名，航班号，座位号(初始为0)，假设已有3个客户信息存入已存放在客户数组customers中。
(2)有新客户订票时，先输入客户的姓名和他订购的航班号，查询该航线的订票情况，若有余票，则为客户办理订票手续，分配给客户一个座位号，然后将新客户的信息添加到数组customer中，并修改数组airline中该航线的订票数和余票数，若无余票，则输出客满信息．
3．退票业务：根据客户提出的航班号，办理退票，从数组customer中删除该客户的信息，并修改文件airline中相应航线的订票数和余票数．
4．输出全部航线信息和全部客户信息．
5．退出系统．
