根据错误的前提回答问题是不可能的。

''throw''不是运营商。为什么你认为它是一个？或者，

而不是，你是什么意思被视为一个运营商？什么是

上下文？

It is impossible to answer a question based on a wrong premise.
''throw'' is not an operator. Why do you think it is one? Or,
rather, what do you mean "considered as an operator"? What is
the context?

出于同样的原因，new，delete和sizeof是运算符，我会怀疑是b
。如果它不是运营商，它还会是什么呢？

For the same reason that new, delete, and sizeof are operators I would
suspect. What else would it be, if it was not an operator?

什么''返回''？ ''throw''就是这样。


''删除''是一个操作符，因为你被允许超载它和

因为这个名字该函数将是''operator delete''。但是其他真正的运算符中的
它很突出，因为它不会产生一个值，因此不能用于另一个表达式。


''throw''是两个构造中使用的关键字：声明列表

函数可以抛出并实际重定向

流。 ''return''不是用来声明任何东西，也不是''goto''。

但''throw''更像是''return''或''goto' '比''sizeof''或

''typeid''。

What''s ''return''? ''throw'' is exactly that.

''delete'' is an operator because you''re allowed to overload it and
because the name of that function would be ''operator delete''. But
among the rest of true operators it stands out because it does not
yield a value and hence cannot be used in another expression.

''throw'' is a keyword used in two constructs: to declare the list
of exceptions the function can throw and to actually redirect the
flow. ''return'' isn''t used to declare anything, neither is ''goto''.
But ''throw'' is much more like ''return'' or ''goto'' than ''sizeof'' or
''typeid''.
