1、精選優質文檔-傾情為你奉上C語言程序設計飛機訂票系統代碼如下：”#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 = * 歡迎進入飛機訂票系統*," a:輸入航線 "," b:查詢航線 "," c:退訂票系統 "," d:追加航線 "," e:刪除航線 "," f: 退出 ","*" ;int i;char NO
