try-catch名称 [英] try-catch name
问题描述
我无法相信自己的眼睛，但到目前为止我还无法找到构造的名称
是什么从一个try块和catch子句
（处理程序）。我不是在寻找一个语法名称，但人们可以记住，就像处理程序一样。但是不是处理程序，因为那些是捕获
子句而且尝试不属于那里。我查看了所有书籍
和标准，但我找不到名字。 ： - （
有没有人知道这个名字？如果有，请与我分享
这里。:-)

Hi,
I cannot believe my eyes, but so far I could not find out what is the name
of the construct, which is built from one try block and the catch clauses
(handlers). I am not looking for a grammar name, but something people can
remember, like handler. But is not handler, because those are the catch
clauses and the try does not belong there. I have looked at all my books
and the standard, but I could not find a name. :-(
Is there anyone who knows that name? If there is, please share it with me
here. :-)

它这叫做试一试。
It''s called a try statement.
谢谢。你能告诉我在哪里可以找到它吗？我试图找到
" try statement"在标准中，在C ++编程语言规范中。
版甚至谷歌。
据我所知，C ++不使用try语句文献（它是在C＃和Python中使用的
），或者在使用它时，它被用作try关键字或try表达式的synonim
，没有其中包含整个
try-and-all-catch的东西。这就是为什么我要求获得
信息的来源，我似乎无法找到它。

Thanks. Could you tell me where can this be found? I have tried to find
"try statement" in the standard, in The C++ Programming Language Spec.
Edition and even Google.
As far as I can see the try statement is not used by C++ literature (it is
used in C# and Python), or where it is used it is used either as the synonim
for the try keyword or the try expression, none of which contains the whole
try-and-all-catch thing. That is why I have asked for source of
information, I cannot seem to find it.

我必须承认，我看了（尽管简短）而且也找不到确定的答案。这就是我如何引用它。语法
将try-block视为语句，将catch处理程序视为
语句，但是如果没有其他语句则将语义错误视为一个语义错误，所以
整个构造在我看来是一个声明。
肯定是整个结构可以用作一个。例如：
if（cond）
试试{
}
catch（.. 。）{
}
我想也许标准调用整个构造异常
处理程序，它包含一个尝试条款和捕获条款。

Well I have to admit, I looked (albeit briefly) and couldn''t find a
definite answer either. That''s just how I would refer to it. The grammar
treats the try-block as a statement and the catch handler as a
statement, but it is a semantic error to have one without the other, so
the whole construct would appear to me to be a statement. It is
certainly true that the whole construct can be used as one. For example:
if (cond)
try {
}
catch (...) {
}
I think maybe the standard calls the whole construct an exception
handler, which consists of a try clause and a catch clause.
