你能给出一个wh的例子在你的意思是''自动指针''？

Can you give an example of what you mean by ''automatic pointer''?

这里只是一个猜测：标准模板类叫做auto_ptr，

也许是是自动的地方。来自...

Just a guess here: the standard template class is called auto_ptr,
perhaps that''s where the "automatic" comes from...

我猜它意味着一个指针在它被销毁时删除托管指针

被销毁，没有允许共享或转让所有权 - 比如

boost :: scoped_ptr。只是一个猜测。

I''d guess it means a pointer which deletes the managed pointer when it
is destroyed, with no sharing or transfer of ownership allowed -- like
boost::scoped_ptr. Just a guess.
