/*任务：通过此系统可以实现如下功能：
录入：可以录入航班情况（数据可以存储在一个数据文件中，数据结构、具体数据自定）
查询：可以查询某个航线的情况（如，输入航班号，查询起降时间，起飞抵达城市，航班票价，票价折扣，确定航班是否满仓）；
可以输入起飞抵达城市，查询飞机航班情况；
订票：（订票情况可以存在一个数据文件中，结构自己设定）
可以订票，如果该航班已经无票，可以提供相关可选择航班；
退票：可退票，退票后修改相关数据文件；
客户资料有姓名，证件号，订票数量及航班情况，订单要有编号。
修改航班信息：当航班信息改变可以修改航班数据文件
要求：
根据以上功能说明，设计航班信息，订票信息的存储结构，设计程序完成功能；*/
