/*码农：成蹉跎内容：模拟航空订票系统，包含对文件的处理。-12-12：一个bug，在没有航班信息表的情况下，添加航班信息之后，输出的航班信息为空。已改正，原因是，航班信息是存储在临时数组里面的，数组的信息在管理员登录的时候添加了依次，但是在管理员添加完信息后并没有更新。航班信息，只是在管理员登录成功，用户登录和管理员添加航班信息时候，才会到文件中去读数据。优化航班信息在文件中的修改，只有用户确定修改一个元组信息的时候，才会把一个完整的新的元组写入文件中。-12-14：新发现一个bug，当没有人退票的时候，显示所有订票信息的时候会出现一个空值。应该是排序算法写错了。已改正，错误原因：进行排序的时候，总的订票人数(index)比实际大1，标记第一个有效订票位置(firstValid)位置正好，混乱了业务不合理部分：在修改航班信息的时候应该给顾客提示信息，需要在顾客结构体中添加一个提示信息属性属性已经添加。在修改航班信息的时候，对相关的顾客提供提示信息。当管理员修改的是飞机号和时间的话，只需要给出提示信息就好了，但是管理员直接修改了航班的出发地和目的地的话，那该航线的所有顾客的飞机票就要作废了。这样的话，在顾客查看自己的机票的时候第一次查看机票，机票是存在的，但是会告诉顾客此机票已经作废，已经退款，再次查询的话就应该是不存在了。以实现。仍需增加的功能：删除航班信息。已经实现，当航班被删除后修改顾客的信息的提示（tips），同时删除航班信息表中的信息-12-16：设置清屏内容，使显示更加简洁，清晰*/#include<stdio.h>//标准输入、输出头文件#include<string.h>//包含字符串函数处理头文件#include<unistd.h>//access
