飞机航班管理系统 愿景&源代码
实训设计课程：飞机航班管理系统
任务：
用C程序设计语言设计一个飞机航班管理系统，能够完成一定的实用功能，比如进行航班信息的输入、查询等等。做到学以致用。
功能介绍：
一个功能菜单显示所有可选功能；
通过一个主函数，调用函数，其他通过分级调用函数完成，调用功能模块：
A.航班信息管理（调用以下函数，进行信息管理）：
- 航班信息输入
- 删除航班信息
- 显示当前所有航班
- 保存所有信息
B.航班信息查询（调用以下函数实现）：
- 按航班号进行查询
- 按终点站进行查询
- 按同时输入的时间终点进行查询
C.对航班信息进行排序（调用以下函数实现）：
- 按飞行时间进行排序
- 按航班号进行排序
D.进行订票（查询航班完毕后，输入航班号进行订购机票）；
E.进行退票（输入航班号进行退票）；
F进行统计相关信息（在输入的时间段内，统计所有已售机票，营业总金额）；
0.退出系统。
主要技术：
- 利用数组
- 调用函数
- 构建结构体
- 定义变量
- 利用顺序结构、选择结构、循环结构
- 使用指针
- 运用预处理命令
- 文件管理实现方法：
通过定义结构体数组，把各航班信息录入进去，然后就可以根据航班号（或终点站、飞行时间）来对结构体变量进行管理（比如录入、删除、订票、退票），通过循环控制，找到相关的信息，确认后就可以通过对地址的操作，达到对结构体数组的管理，然后输出显示。
通过函数的嵌套调用、递归调用，达到要求的功能，让源代码的直观性更加强大，安全性，可修改性更加高。有利于源代码的阅读、修改、优化。
合理地利用全局变量，让程序的实用性、可靠性更高，使用函数原型的方式对函数进行声明，把函数原型放在一块，更好管理函数模块。
额外加入了“密码管理“，通过密码管理，可以增强航班管理系统的安全性能，也可以修改密码，修改的密码以文件的信息录入磁盘，所以修改的密码在下次使用依然奏效。当管理员输入密码后，可以得到旅客所不具有的权限，比如能录入航班信息，删除航班等等。
用了文件管理的方法，对录入的信息进行保存，然后就算停止运行释放了内存，在下次登录的时候，进行读操作，把上次录入保存到磁盘的信息重新录入到内存中，直接利用存取；达到文件管理的效果，让航班管理系统的功能更加强大，让系统的实用性更加高。
