switch (grade)
{case 10:
case 9: printf(“grade=A\\n”); break;
case 8: printf(\"grade=B\\n\"); break;
case 7: printf(\"grade=C\\n\"); break;
case 6: printf(\"grade=D\\n\"); break;
case 0: printf(“grade=E\\n”); break;
default: printf(“The score is out of range!”);
}
如果grade的值不为10,9,8,7,6,0 输出The score is out of range!本回答被网友采纳

默认 打个换行符。应该是在switch语句里的吧。。。
