為啥輸出的是D
#include <stdio.h>
int main()
{
??? int score = 87; //考試分數為87分
???
??? switch(score)
??? {
??????? score=score/10;
??????? /*想想以下代碼為什么用這種方式；
????????? 這種方式的好處？*/
??????? case 10:
??????? case 9:
??????????? printf("等級A");
??????????? break;
??????? case 8:
??????????? printf("等級B");
??????????????????? break;??????? //這里是不是缺點什么？???????????
??????? case 7:
??????? case 6:
??????????? printf("等級C");
????????????????????? break;????? //這里是不是缺點什么？?
??????? default:
??????????? printf("等級D");
??????????? break;???
??? }
??? return 0;
}

哪位大神解釋一下為什么要加score/10
2016-12-18
所以switch直接跳到default

score沒有處理成score=score/10
