C ++：有人可以向我解释一个C / Hw的家伙，参考（&）和指针之间的区别是什么？ [英] C++: can someone explain to me, a C/Hw guy, what the diff is between a reference (&) and a pointer?

问题描述

为什么以及在哪里应该使用哪一个？


口头上，对我来说似乎是语义 - 但显然有一些

实际差异使得参考文献不同或者更可取

在某些情况下超过指针...


TIA

And why and where one should use one vs. the other?

Verbally, it seems like semantics to me--but obviously there is some
actual difference that makes references different and or preferable
over pointers in some cases...

TIA

参考文献更容易优化。

我没有找到特别常见问题有用。更确切地说，我相信它

充满了（很好地称为）废话。


你认为它有用吗？
