Question

关于C语言多分支选择结构switch case，急！例题如下，请问我哪里做错了呀？·

EG:从键盘上输入一个百分制成绩score，按下列原则输出其等级：score≥90，等级为A；80≤score<90，等级为B；70≤score<80，等级为C；60≤score<70，等级为D；score<60，等级为E。
main(){ int score; char grade; printf("input a score(0~100)\n"); scanf("%d",&score);
switch (score/10) { case 0:printf("grade=E\n");break; case 1: case 2: case 3: case 4: case 5: case 6:printf("grade=D\n");break; case 7:printf("grade=C\n");break; case 8:printf("grade=B\n");break; case 9:printf("grade=A\n");break; case 10: default: printf("The score is out of range!\n"); } getch();}

Answer 1

void mian(){
int score;
char grade;
printf("input a score(0~100)\n");
scanf("%d",&score);
switch (score/10) {
case 0:case 1:case 2:case 3:case 4: case 5:
printf("grade=E\n");break;
case 6:
printf("grade=D\n");break;
case 7:
printf("grade=C\n");break;
case 8:
printf("grade=B\n");break;
case 9:
printf("grade=A\n");break;
default:
printf("The score is out of range!\n");
}
}
