请帮我看看哪错了？
#include<stdio.h>main()
{
int score, grade,;
printf("请输入分数:\n");
scanf("%d",&score);
grade = score / 10;
switch(grade)
case 10:
case 9:printf("grade is A\n");break;
case 8:printf("grade is B\n");break;
case 7:printf("grade is C\n");break;
case 6:printf("grade is D\n");break;
case 5:
case 4:
case 3:
case 2:
case 1:
case 0:printf("grade is E\n");break;
}
我找了好长时间确实找不出来。
