swith程序,按照书本中输入，缺运行不了？？请大家帮忙看看
提示错误在第二个大括号处，经检查，无异常。。。#include<stdio.h>
main()
{
int score;
printf("\nplease enter score(score<=100):");
scanf("%d",&score);
if(score==100)
score=90;
score=score/10;
swith(score)
{
case 9:
printf("A");
break;
case 8:
printf("B");
break;
case 7:
printf("C");
break;
case 6:
printf("D");
break;
default:
printf("E");
}
}
