This concerns the Wikipedia article on C and C++ operators:
http://en.wikipedia.org/wiki/Operators_in_C_and_C%2B%2B
Until very recently the first table in the page was a very
useful one on the precedence of C operators. This has
recently been replaced by one on C++ operators. I''m
not at all happy with that but I guess I can always link
to the history page. But I was wondering if anyone could
have a look and verify that the C part is correct. I''m pretty
sure that in C postfix/prefix increment/decrement have
the same priority. Is it different in C++ ?
By the way here''s the page I have been using:

但我想知道是否有人可以
查看并验证[维基文章]的C部分是否正确。

没有意义。即使它今天恰好是正确的,今晚也可能会错误的是
。

No point. Even if it happens to be correct today, it could be wrong again by
this evening.

这是什么意思?究竟是什么具有相同的优先级?
例如,前缀增量和前缀减少在
C和C ++中具有相同的优先级,但这并不重要,因为没有
上下文,因为它们都很重要(因为两者都是_prefix_)。这同样适用于
后缀运算符。
当谈到一元运算符时,优先级问题也是如此。仅当我们将
比较前缀运算符和后缀运算符时才存在。在C和C ++中,后缀一元
运算符通常比前缀运算符具有更高的优先级。

What do you mean by this? What exactly has "the same priority"?
Prefix increment and prefix decrement, for example, do have the same priority in
both C and C++, but this is not really something important because there is no
context where it would matter (since both are _prefix_). The same applies to
postfix operators.
When it comes to unary operators, the issue of "priority" only exists when we
compare a prefix operator to a postfix one. And in both C and C++ postfix unary
operators normally have higher priority than prefix ones.

在C ++中,postfix的优先级高于前缀。表格似乎很好
那里。
我确信在C中它是一样的。
存在循环依赖在三元和任务之间,表格
只是
无法反映出来。
In C++ postfix has higher precedence than prefix. The table seems fine
there.
I am certain that in C it is the same.
There is a circular dependency between ternary and assignment, the table
simply
cannot reflect that.
