char数组初始化：'char a [] =（" a"）'有效ANSI C？ [英] char array initialization: Is 'char a[] = ("a")' valid ANSI C?
问题描述
代码片段''char a [] =（" a"）;''有效的ANSI C？
有问题的部分是''（a）''。我确定''char a [] =" a" ;;''有效
ANSI C，但我更不确定是否允许放置（）围绕
字符串文字。
Is the code fragment ''char a[] = ("a");'' valid ANSI C? The
problematic part is ''("a")''. I am sure ''char a[] = "a";'' is valid
ANSI C, but I am more unsure if it is allowed to place () around the
string literal.

是的。我无法想象在表达式周围放置
括号是非法的。

有时候我觉得拍摄对某些人来说太好了。
虽然我的电子邮件地址说垃圾邮件，但它是真实的，我读了它。
Yes it is. I can''t think of any situation where it is illegal to put
brackets around an expression.

Sometimes I think shooting would be far too good for some people.
Although my email address says spam, it is real and I read it.

您的意思是说括号吗？ "托架"是''[''和'']''，
至少用我熟悉的说法。
第二个想法，字典.com说括号可以表示
括号用英式英语是一个或另一个标准，或
我们是否像其他许多地方一样受到方言的支配？

Did you mean to say "parentheses"? "Brackets" are ''['' and '']'', at
least in the parlance I''m familiar with.
On second thought, dictionary.com says "bracket" can mean
"parenthesis" in British English. Is one or the other standard, or
are we at the mercy of dialect here as in many other areas?

在我个人的英语方言中，术语是（括号），
[方括号]和{大括号}。其他方言可能有所不同。我认为
术语括号是明确的，但如果有任何疑问，那么最好使用[方括号]和{花括号}来引用b $ b。更好的是，使用
字符本身。

我们必须做点什么。这是事情。因此，我们必须这样做。
In my personal dialect of English, the terms are (parentheses),
[brackets], and {braces}. Other dialects may differ. I think the
term "parentheses" is unambiguous, but if there''s any doubt it''s best
to refer to [square brackets] and {curly braces}. Better yet, use the
characters themselves.
