（已修改，请用最新的代码）代码说明：
1级菜单：选择购买的航班号，并显示对应座位状态。
（我只做测试，所以初始化initFlight函数中我只初始了2个航班，需要自己按照我的代码添）
（注意：实际开发软件，链表数据是从数据库中读取的，需要实时同步，如果要多次调用initFlight函数，记得自己写一个释放内存的函数，把所有链表“SINFO和FLINFO”节点都释放掉，释放函数我没写，需要你自己写！！！）
2级菜单：选择购买对应座位号，完成购买，并实时显示购买结果。
位置编号、座位最大排数、舱室类型、折扣等参数均由常量参数空值，需要修改自行改常量。
注意：舱室类型（我默认3个类型头等舱、公务舱、经济舱）对应折扣消和梁参数：tDiscount二维数组。如要如要添加新的舱室类型，必须将参数常量TYPESIZE、typeName、types、tDiscount这4个同时修改，具体看代码备注！！
座位票价=基础票价棚戚*类型折扣*时段折扣。
因为飞机不让吸烟，所以我没做吸烟区（笑），如果你需要，可以作为类型自行添加！
