用case 语句做啦`````

用的是switch--case语句做的：#include int main(void) {
int score,count;
printf("Input a number please:\n");
scanf("%d",&score);
count=(int)(score-5)/10; switch(count){
case 9: printf("Your score is A\n"); break;case 8: printf("Your score is B\n"); break;case 7: printf("Your score is C\n"); break;
default: printf("Your score is D\n"); break; }
return 0;}一下是部分测试结果：(1)Input a number please:95Your score is APress any key to continue(2)Input a number please:94Your score is BPress any key to continue(3)Input a number please:74Your score is DPress any key to continue
