参考如何在内部实现? [英] How are references implemented internally?

问题描述

我只是想知道如何在不同的编译器和调试/发布配置中实际实现引用.该标准是否提供有关其实施的建议?实现有区别吗?

I'm just wondering how references are actually implemented across different compilers and debug/release configurations. Does the standard provide recommendations on their implementation? Do implementations differ?

我试图运行一个简单的程序，在该程序中我从函数返回非常量引用和指向局部变量的指针，但是它们的工作方式相同.这是否意味着引用在内部只是一个指针?

I tried to run a simple program where I return non-const references and pointers to local variables from functions, but they worked out the same way. Does this mean that references are internally just a pointer?

推荐答案

引用的自然实现确实是一个指针.但是，请不要在您的代码中依赖它.

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