switch (x/10)
{
if(x/10>10) printf("wrong score inputed!");break; \*排除错误的分数输入，使得分数严格在100-0分内。*\
case 10:printf("Grade is A\n");break; \*100情况*\
case 9:printf("Grade is A\n");break; \*90-99分*\
case 8:printf("Grade is B\n");break; \*80-89分*\
case 7:printf("Grade is C\n");break; \*70-79分*\
case 6:printf("Grade is D\n");break; \*60-69分*\
defult:printf("Grade is E\n");break; \*60分以下*\
}
自己写的，不要见笑。
