#include <stdio.h>
void main ()
{
   int weekday;
   printf("今天的食谱\n 请输入星期几\n");
   scanf("%d",&weekday);
   switch (weekday)
   {
        case 1:printf("星期一:青菜\n");
			break;
		case 2:printf("星期二:鸡\n");
			break;
		case 3:
			printf("星期三:鱼\n");
			break;
		case 4:
			printf("星期四:肉\n");
			break;
		case 5:printf("星期五:鸡蛋\n");
             break;
		case 6:
			printf("星期六:海鲜\n");
			break;
		case 7:
			printf("星期日:豆制品\n");
			break;
		default:
			printf("输入有误\n");
			break;
   }
