课程设计做一个飞机订票系统，c语言实现，功能如下：
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；
写惯了控制台程序，所以打算做个界面出来，时间也很充裕，于是就自学了windows API，开发环境为vs2013。

具体实现代码见下篇博文吧，写代码的过程中还是遇到不少问题的。先附几张程序效果图，包含了一些个人二次元爱好….
