auto_ptr内存泄漏与数组？ [英] auto_ptr memory leak with arrays?

问题描述

我正在阅读 http：/ /www.kuro5hin.org/story/2005/10/31/53857/831

auto_ptr使用" delete"在它的析构函数而不是delete []。

文章是最新的，所以我想知道这对于任何托管实现是否一般都是真的

。

Hi, I was reading on http://www.kuro5hin.org/story/2005/10/31/53857/831
that auto_ptr uses "delete" in its destructor instead of delete[]. The
article is fairly recent, so I was wondering if this is true in general
for any hosted implementation.

是的，这是真的，我也遇到过这个问题，所以我最初复制了

并粘贴了一个auto_ptr实现并更改了一行删除[]。


但是现在我使用了boost ，我认为这是一个好主意。看看boost smart

指针，如boost :: scoped_array。

Yes this is true, I also encountered this problem, so I originally copied
and pasted a auto_ptr implementation and change the one line to delete[].

But now I use boost, which I think a far better idea. Look at boost smart
pointers such as boost::scoped_array.

只需使用向量。

魔术取决于传统和信仰。它不欢迎观察，

也不会通过实验获利。另一方面，科学的经验基于
;它可以通过观察和实验来纠正。

Just use a vector.

on experience; it is open to correction by observation and experiment.

如果你需要一个数组，那么你不应该使用auto_ptr，并且

而是使用std :: vector。

auto_ptr表示单个对象，std :: vector表示

多个对象。

If you need an array, then you should not be using auto_ptr, and
instead use std::vector.

auto_ptr represents a single object, and std::vector represents
multiple objects.
