设计不一致？ [英] Inconsistency by design?
问题描述
我多年来一直在使用C ++，我认为我对它非常称职，但今天我只是注意到调用构造函数存在一些不一致的地方。如果你使用一个没有参数的构造函数，那么看来你必须在声明之后不要在括号之间加上任何东西。
示例：
I''ve been using C++ for years, and I thought that I was quite competent with it, but today I just noticed that there is something of an inconsistency with calling a constructor. If you use a constructor that has no parameters, then it appears that you must never put parentheses with nothing in between after the declaration.
Example:
推荐答案
- 在g ++ 上我得到了一种''foo（ ）（）''，甚至连编译器都不知道该怎么做的类型。
- VC ++ 6.0给了我一个'致命错误C1001：内部编译器错误''。
- On g++ I got a type of ''foo()()'', a type that not even the compiler knows quite what to do with.
- VC++ 6.0 gave me a ''fatal error C1001: INTERNAL COMPILER ERROR''.
评论任何人？
Comments anyone?
我所知道的是，在使用默认参数初始化对象时，我读过永远不会使用一组空的括号 - 我从来没有费心去看过如果我没有会发生什么。
All I know is that I''ve read never to use an empty set of parentheses when initializing an object using the default parameter - I''ve never bothered seeing what would happen if I didn''t.
看来，如果你把++（两个连续性）加入并且它不在某些标签中斜体，当我提交或预览帖子时，它会将我发送到未找到页面页面...如果负责人可以解决这个问题，那么它会阻止人们在尝试发布时拔掉头发。 ;）
我遇到了同样的问题，所以还有其他几个用户。请放心，我们正努力尽力解决问题。
I''ve had the same problem, and so have a couple other users. Rest assured, we are working to try and fix the problem as best as we can.

你在哪里读到的？我不确定自己为什么我没有把空括号除外，因为我发现它不能正常工作。我发现这很有意思。
Where did you read that? I''m not sure myself about why I don''t put the empty parentheses except that I probaby found it not to work properly. I just find that interesting.

也许在论坛顶部放一个便利贴，或者如果你能修改消息输入页面，请在那里快速记下它？至少人们不会为此而烦恼并避免这个问题。

Perhaps putting a sticky note at the top of the forum or if you are able to modify the message entry page, put a quick note about it there? At least people won''t be scratching their heads about it and avoid the problem.
