指针q [英] pointer q
问题描述
我最近的一篇文章显示，指针上有足够大的失态，因为
需要返回K& R 5.1-6附录A8.6.1。所以我们有类型说明符：
int
long
..一个梦想自己变量名称：qwe，qwr，写道
< br $> b $ b int qwe;
long qwr;
并认为他知道他宣布的是什么类型。你问过我关于 的信息：
int * qwe;
long * qwr;
我会说声明的指针是 - 虽然指向不同的
类型 - 相同类型。为什么我错了？ Joe
A recent post of mine showed a sufficiently large gaffe on pointers as to
need to return to K&R 5.1-6 appendix A8.6.1 . So we have type specifiers:
int
long
.. One dreams himself variable names: qwe, qwr, writes
int qwe;
long qwr;
and thinks he knows what types he''s declared. Had you asked me about:
int *qwe;
long *qwr;
I would have said the pointers declared were--while pointng to different
types--of the same type. Why am I wrong? Joe

" qwe"类型为指向int的指针。
" qwr"类型为指向长指针。
这些是不同的类型。

如果我告诉过你有一次，我已经告诉过你LLONG_MAX次不要夸大了夸夸其谈。

"qwe" is of type "pointer to int".
"qwr" is of type "pointer to long".
Those are different types.

int *和long *是两种不同的类型（两种指针类型）。
我很好奇，是什么导致你认为他们是同一类型的？

我们必须做点什么。这是事情。因此，我们必须这样做。
int* and long* are two different types (both pointer types).
I''m curious, what led you to think that they''re the same type?

We must do something. This is something. Therefore, we must do this.
