为什么连字符选为C ++中引用的符号？ [英] Why was the ampersand chosen as the symbol for references in C++?

问题描述

有没有人有，为什么符号被选为表示用C ++引用的方式的想法？

Does anyone have an idea why the ampersand was chosen as the way to denote references in C++?

据我所知（尽管我没有这本书在我身边），Stroustroup没有解释这样的选择，我觉得有些奇怪，因为相同的符号已经被用在C地址的。

AFAIK (though I don't have the book near me), Stroustroup didn't explain that choice, which I find a little odd because the same symbol was already used for address-of in C.

推荐答案

斯特劳斯总是很不愿意引入新的保留符号或名称，所以他很可能用它来避免使功能看起来很怪异到C的用户。

Stroustrup was always very reluctant to introduce a new reserved symbol or name, so he probably used it to avoid making the feature look weird to users of C.
