解题思路:

注意事项:

参考代码:

#include<stdio.h>

void main()

{

int score,grade;

while((scanf("%d",&score))!=EOF)

{ grade=score/10;

switch(grade)

{case 10:

case 9:printf("A\n");break;

case 8:printf("B\n");break;

case 7:printf("C\n");break;

case 6:printf("D\n");break;

case 5:

case 4:

case 3:

case 2:

case 1:

case 0:printf("E\n");break;

default:printf("Score is error!\n");

}

}
