内部如何实现引用？ [英] How is reference implemented internally?

问题描述

只是想知道它是如何实现跨不同的编译器和调试/发行配置。标准是否对其实施提出了建议？

Just wonder how is it implemented actually across different compilers and debug/release configurations. Does standard somehow provides recommendations on its implementation? Does it differ anywhere?

我试图运行一个简单的程序，我已经从函数返回非const引用和指向局部变量的指针，但它的工作方式是一样的。所以是真的，内部引用只是一个指针？

I tried to run a simple program where i have been returning non-const references and pointers to local variables from functions but it worked out the same way. So is it true that reference internally is just a pointer?

推荐答案

引用的自然实现确实是一个指针。但是，在您的代码中不要依赖于此。

The natural implementation of a reference is indeed a pointer. However, do not depend on this in your code.
