购票程序
机票购票系统是为客户购票服务及个人购票信息查询和维护的系统，该系统至少能够实现：
（1） 航班信息读取。本系统不涉及航班信息及票价管理。开始购票前，管理员只需要从指定数据文件导入当前运行的航班信息即可。
航班信息：航班编号、航线编码、起飞时间、可售机票总数、票价、当前状态（准
备、已出票、售完、已结束）。
（2） 查询功能。可以根据起飞时间、始发地和到达地、航班号、订票人数进行组合查询，
查询结果根据用户选择进行排序输出。
（3） 购票功能。用户登录系统后，如果航班状态允许，可以进行：
a) 购票。购票信息同步到数据文件。
b) 退票。退票信息同步到数据文件。
（4） 个人信息管理。用户可以修改密码，查询个人订票记录。
（5） 系统以菜单方式进行操作
