什么是C ++中的引用变量？ [英] What is a reference variable in C++?

问题描述

在C ++中引用变量的简短定义是什么？

What would be a brief definition of a reference variable in C++?

推荐答案

是一个实体，是另一个对象的别名。

A reference is an entity that is an alias for another object.

/ em>作为变量仅由对象的声明引入。 对象是存储区域，在C ++中，引用不一定占用任何存储空间。

A reference is not a variable as a variable is only introduced by the declaration of an object. An object is a region of storage and, in C++, references do not (necessarily) take up any storage.

作为对象和引用是C ++中不同的实体组，因此术语引用变量没有意义。

As objects and references are distinct groups of entities in C++ so the term "reference variable" isn't meaningful.
