该系统用了三个文件来写main.c文件Flight_system.h头文件Flight_system.c文件。mian.c文件主要调用Fligth_system.c文件的各个函数功能Flight_system.h文件主要编写航班管理系统的功能的定义Flight_system.c文件主要编写航班系统的各个功能的实现以及初始化该系统分为管理员和用户模式。需要管理员添加航班信息用户才能购买。管理员是提前定义好的管理员账户TJC密码是123登录时不验证密码如需验证可在登录模块中自行添加判断语句。管理员登录后有1.添加航班2、删除航班。3、修改航班。4、查询航班。4个功能。需要先添加航班信息该系统才能激活各个模块。当然也对应着各个模块的错误反馈。用户模式用户在管理员添加航班后有4个功能。1、查询航班。2、购票。3、退票。4、改签。代码main.c文件#includeFlight_system.cint main(){Customer *pArr NULL;Customer *p NULL;pArr (Customer *)malloc(9*sizeof(Customer));//注册的用户较多就改变9的值p pArr;Plane *qArr NULL;Plane *q NULL;qArr (Plane *)malloc(9*sizeof(Plane));//注册的航班较多就改变9的值q qArr;int mkWellcome();while(1){switch(mk){case 1 :Estimate(p,User_num,q,Plane_num);break;case 2 :Input(p,User_num);
