[問題] 面試看到的一題
看板C_and_CPP (C/C++)作者wilson50101 (我覺得我還不錯啊)時間9年前 (2017/01/26 16:21)推噓11(11推 0噓 24→)留言35則, 12人參與討論串1/1
typedef struct{
int x;
int y;
}point;
void fun(point*);
void main()
{
point p;
p.x=12;
p.y=10;
fun(&p);
}
void fun(point *p)
{
p->x++;
p->y--;
}
這是我今天面試某bios出的題目 趁印象還深快上來發問 程式碼大概就是上述這樣(沒有完全背下來)
Q:fun(*p)改成fun(&p)然後p值要一樣要怎麼改
我是寫
void fun(point&p)
{
(**p).x++;
(**p).y--;
}
面試官說這只有c++能這樣用而且這樣好像也不對
可是回家用devc++跑void fun(point&p)
一直編譯沒過
想請問這樣是要怎麼改 還是牽涉到什麼觀念
