C语言程序设计-飞机订票系统

1、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 inp ut(); void search(); void preserve。； void plane

2、add(); void delplane();void main()sys tem(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;int quit 二 0;do sys tem(cls);for (i = 0; i9; i+)pri ntf (n%s, menui);prin tf(n 请输入服务代码 a,b,c,d,e 或fn);NO = get char();switch (NO)casea: input(); break;ca

3、seb: search。； break;casec : preserve。； break;cased : planeadd(); break;casee : delplane(); break; casef : quit 二 1; break; while (!quit);void inp ut()int i, n;FILE *fp;sys tem(cls);if (fp = fopen(D:file, wb) = NULL)printf(error!n); exit(0);prin tf( n请输入航班总数n:); scanf(%d, &n);prin tf(n请按下面提示输入航班信息：起点

4、站：沈阳)； for (i = 0; in; i+)printf(nt请输入终点：); scanf(%s, ai.des tination); printf(t 航班班次：);scanf(%s, ai.num); printf(t 时间：)； scanf(%s, ai .ti me);printf(t 票价：)； scanf(%d, & ai.price);printf(t机票总数：); scanf(%d, & ai.amou nt);fwrite(&ai, sizeof(PLANE), 1, fp);fclose(fp);void search()int i, j = 0, k = 101;

5、char st r12;FILE *fp;PLANE b5;if (fp = fopen(D:file, rb) = NULL) printf(error!n);exi t(0);printf(n请输入航班号：)； scanf(%s, st r);while (fread(&bj, LEN, 1, fp) != 0)j+;for (i = 0; ij; i+)if (st rcmp(bi.num, str) = 0) printf(“沈阳至%s航班号：%s时间：%s票价：%d剩余票数：%dn, bi.destination, bi.num, bi.time, bi.price, bi.amou

6、 nt);k = i;if (k = 101)printf(对不起，没有您需要的航线。)； fclose(fp);system(pause)；void preserve。int a = 0, i = 0, k, m, n, x;char st r12;PLANE preserve10;FILE *fp;if (fp = fopen(D:file, rb) = NULL) printf(error!n);exi t(0);printf(请输入航班号：); scanf(%s, st r);while (fread(&preservei, LEN, 1, fp) != 0) if (st rcmp(

7、preservei.num, str) = 0)printf(“沈阳至%s航班号：%s 时间：%s 价格：%d 剩余票数：%d, preservei.destination, preservei.num, preserved.time, preservei.price, preservei.amou nt);k = i; i+;fclose(fp);printf(n请输入订退票代码：0-订票1-退票“)； scanf(%d, & m);if (m = 0) printf(“沈阳至%s航班号：%s时间：%s价格:d元 剩余票数：%d, preservek.des tination, preser

8、vek.num, preservek .ti me, preservek.price, preservek.amou nt);prin tf(n请输入订票总数n:);scanf(%d, &n);x = preservek.price*n;prin tf(n 应付款 %d 元，x); preservek.amou nt 二 preservek.amou nt n; printf(n订票成功！祝您旅途愉快！);if (m = 1)prin tf(n请输入欲退票数n:); scanf(%d, &n);x = preservek.price*n;prin tf(n 应退金额:d 元，x); prese

9、rvek.amou nt 二 preservek.amou nt + n; printf(n退票成功!);fp = fopen(D:file, wb);for (i = 0; i = k; i+)fwrite(&preserved, LEN, 1, fp); fclose(fp);system(pause);void planeadd()int x, k = 1;PLANE planeadd;FILE *fp;do prin tf(n请按下面提示输入新增航班信息:); printf(t请输入终点：)； scanf(%s, planeadd.des tination);prin tf(t请输入航

10、班号：)； scanf(%s, planeadd.num);printf(t请输入时间：)； scanf(%s, planeadd .ti me);prin tf(t请输入价格：，planeadd.price); scanf(%d, & planeadd.price);prin tf(n请输入机票总数:)； scanf(%d, & planeadd.amou nt);if (fp = fopen(D:file, ab+) = NULL) prin tf(“文件有错误不能打开!)； exi t(0);fseek(fp, LEN, 2);fwrite(&planeadd, LEN, 1, fp);

11、 fclose(fp);prin tf(n增加信息成功)；printf(n是否继续增加航班？继续请输入1,否则输入0返回主菜单。); scanf(%d, & x);while (x != 0 & x != 1)printf(n您的输入有误，请重新输入0或1!); scanf(%d, & x);if (x = 0)menu(); k = 0;if (x = 1) k = 1; while (k);void delplane()char st r12;FILE *fp;int total = 0;int i 二 0;int del = 0;PLANE delplane10;if (fp = fopen(D:file, rb) = NULL) prin tf(“文件有错误不能打开!)；exi t(0);prin tf(请输入要删除的航班号:)； scanf(%s, st r);while (fread(&delplane tot al, LEN, 1, fp) total+;for (i = 0; itotal; i+)if (st rcmp(delplanei.num, str) = 0) break;for (; itotal; i+)delplanei = delplanei + 1; total = total - 1;del = 1;prin tf(n成功
