C语言实现航班管理系统代码分享

/*.航班管理系统主界面以菜单的形式展现，用户可以按不同的键执行不同的操作，即调用不同的函数； ...... 用不同的函数实现，除以下模块，还可设计其他功能模块：1）输入记录：输入录入航班信息，包括：航班号，起降时间，起飞抵达城市，航班票价，票价折扣，航班是否满仓等；2）输出记录：输出信息；3）查询记录：可根据航班号查找记录；4）删除记录：指定航班号删除该条记录；5）插入记录：在指定位置插入新的记录。*/#include<stdio.h>#include<stdlib.h>#include<string.h>#define N 50 int menu();int input(struct );void print(struct );void search(struct flight_info info[],int n);int find_id(struct flight_info info[],int n,char *p);int del(struct,int n);int add(struct ,int n);//菜单int menu(){int i=1,choie;// struct flight_info *info;printf("******************航班管理系统*********************\n");printf("\t\t%d.输入航班信息\n",i++);printf("\t\t%d.输出航班信息\n",i++);printf("\t\t%d.查询记录\n",i++);printf("\t\t%d.删除记录\n",i++);printf("\t\t%d.插入记录\n",i++);printf("\t\t%d.退出系统\n",i++);printf("****************************************************\n");do{printf("请输入你所选功能（1～6）：");scanf("%d",&choie);
