利用switch语句编写一个程序，用户从键盘输入一个数字。如果数字为1~5，则打印信息：You wntered 5 or below!;如果数字为6~9，则打印信息：You entered 6 or higher!;如果输入其他，则打印信息：Between 1~9,please!
#include<stdio.h>
void main()
{
int a;
printf("请输入:");
scanf("%d",&a);
switch(a){
case 1:
printf("You entered 5 or below\n");
break;
case 2:
printf("You entered 5 or below\n");
break;
case 3:
printf("You entered 5 or below\n");
break;
case 4:
printf("You entered 5 or below\n");
break;
case 5:
printf("You entered 5 or below\n");
break;
case 6:
printf("You entered 6 or higher\n");
break;
case 7:
printf("You entered 6 or higher\n");
break;
case 8:
printf("You entered 6 or higher\n");
break;
case 9:
printf("You entered 6 or higher\n");
break;
default:printf("Between 1~9,please!\n");
}
}
