参考和指针 [英] References and pointers
问题描述
嗨 -
引用（&）有什么意义？为什么我们不只是使用
指针（*）？
谢谢。
Hi -
What''s the point of having references (&)? Why don''t we just use

在C中，它们不存在。我建议你从
交叉插件中删除comp.lang.c。
In C, they don''t exist. I suggest you remove comp.lang.c from the
crosspost.

我们这样做。

我认为它们存在于某些版本的C中，例如lcc-win也是

I believe they exist in some versions of C, e.g. lcc-win which also
supports Operator Overloading.

语言中添加了引用，以方便运算符重载
in C ++。他们甚至存在于C？
References were added to the language to facilitate operator overloading
in C++. Do they even exist in C?

确实没有必要将它发布到comp.lang.c.在C中我们没有
引用，所以这个问题毫无意义。如果你的目标实际上是b $ b了解使用这些的C ++的基本原理（并且有一个，
虽然这是因为我们在comp中的C ++的其他功能。 lang.c
不太开心），comp.lang.c ++中的人应该能够帮助
。然而，你的交叉意味着你的目标是开始另一场毫无意义的语言战;如果是这样的话，我希望没有人能够接受诱饵。
后续行动仅限于comp.lang.c ++，其中实际上问题是
是有意义的。
There really was no need to post this to comp.lang.c. In C we have no
"references", so the question is pointless. If your aim is to actually
learn about the rationale for C++ using these (and there is one,
although it is because of other features of C++ that we in comp.lang.c
do without quite happily), the folks in comp.lang.c++ should be able to
help. However, your crossposting suggests that your aim is to start
another pointless language war; if so, I hope no one rises to the bait.
Follow-ups restricted to comp.lang.c++, where the question actually
makes sense.
