#include <stdio.h>
int main()
{
int score, m;
scanf("%d", &score);
while (score < 0 || score > 100){
printf("Error! Retry!\n");
scanf("%d", &score);
}
m= score / 10;
if (m>= 9)
printf("Grade is A!\n");
switch(m){
case 0: printf("Grade is E!\n"); break;
case 1: printf("Grade is E!\n"); break;
case 2: printf("Grade is E!\n"); break;
case 3: printf("Grade is E!\n"); break;
case 4: printf("Grade is E!\n"); break;
case 5: printf("Grade is E!\n"); break;
case 6: printf("Grade is D!\n"); break;
case 7: printf("Grade is C!\n"); break;
case 8: printf("Grade is B!\n"); break;
}
return 0;
}
扩展资料：
其他实现输出成绩等级‘A'、’B‘、'C'、‘D'、'E’。90分以上为A,80~89分为B，70~79分为C，60~69分为D，60分一下为E的方法：
#include <stdio.h>
int main()
{
int score;
scanf("%d", &score);
while (score < 0 || score >100){
printf("Error! Retry!\n");
scanf("%d", &score);
}
if (score < 60)
printf("Grade is E!\n");
else if (score >= 60 && score < 70)
printf("Grade is D!\n");
else if (score >= 70 && score < 80)
printf("Grade is C!\n");
else if (score >=80 && score < 90)
printf("Grade is B!\n");
else
printf("Grade is A!\n");
return 0;
}

main()
{
int num;
printf("qing shu ru yi ge cheng ji:");
scanf("%d", &num);
if(num>=0&&num<=100) {
switch (num/10)
{
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;
default: printf("E\n");break;
}}
else
printf("qing shu ru zheng que de fen shu:");
getch();
}
