C语言程序设计——飞机订票系统(共7页)

1、精选优质文档-倾情为你奉上C语言程序设计飞机订票系统代码如下：”#include "stdio.h"#include "stdlib.h"#include "string.h"#define LEN sizeof (struct plane)#define MAX 10;struct planechar destination12;char num10;char time12;int price;int amount;typedef struct plane PLANE;PLANE a100;void menu();void inpu

2、t();void search();void preserve();void planeadd();void delplane();void main()system("cls");menu();void menu()char *menu = * 欢迎进入飞机订票系统*," a:输入航线 "," b:查询航线 "," c:退订票系统 "," d:追加航线 "," e:删除航线 "," f: 退出 ","*" ;int i;char NO
