后增量和预增量超载 [英] Post-Increment and Pre-Increment Overloading
问题描述
你好：
在C ++中，你必须在
重载时区分post和pre增量。有人能给我一个简短的演示，说明如何写这些吗？
我得到的印象是用相同的重载来处理的，但我是/ br / >
只是想确定。
Hello:
In C++, you had to distinguish between post and pre increments when
overloading. Could someone give me a short demonstration of how to
write these?
I get the impression that are handled with the same overload, but I
just want to make sure.

怎么写哪个？ C ++版本？或者是C＃版本？
How to write which? The C++ versions? Or the C# version?

据我所知，您的印象是正确的。你可以重载一个++
运算符。在你提出C ++行为之前，我甚至没有考虑过它可能会出现的其他可能性。

As far as I know, your impression is correct. There is a single ++
operator you can overload. Until you brought up the C++ behavior, I
never even gave much thought to the possibility it might be otherwise.

我不知道.Net-land，但在原生C ++中，前/后增量
运算符是2个独立的运算符。 />
class xyzzy
{
....
xyzzy& operator ++（）//前缀
{
// todo：递增此
返回* this;
}
xyzzy operator ++（int）// postfix
{
xyzzy tmp（* this）;
// todo：增加这个
返回tmp;
}
};
Dave Connet
I don''t know about .Net-land, but in native C++, the pre/post-increment
operators are 2 separate operators.
class xyzzy
{
....
xyzzy& operator++() // prefix
{
// todo: increment this
return *this;
}
xyzzy operator++(int) // postfix
{
xyzzy tmp(*this);
// todo: increment this
return tmp;
}
};

是的，当然是。 OP和我都承认这一点。而且我认为如果OP要求如何在C ++中声明这样的话，那么你的帖子
将与那个问题相关（但不是我要求的那个） -topic
这个新闻组）。
Yes, of course they are. Both the OP and I acknowledged that. And I
suppose if the OP is asking for how to declare such in C++, your post
would be relevant to that question (but not what I''d call on-topic in
this newsgroup).
