C ++覆盖...覆盖？ [英] C++ Overriding... overwriting?

问题描述

我知道C ++中的覆盖是什么。但是，是否有覆盖？

解决方案

在C ++术语中，您有重写（与类层次结构中的虚拟方法有关）和重载（与具有相同名称但采用不同参数的函数相关）。您还可以隐藏名称（通过在嵌套声明区域或作用域中显式声明相同的名称）。

C ++标准不除非使用其规范的英语形式（即，用一个新值替换一个值，如在重写前一个值的赋值 x = 10 中使用术语覆盖 x ）。

I know what overriding is in C++. But, is there overwriting? If so, what does it mean?

Thanks.

解决方案

In C++ terminology, you have overriding (relating to virtual methods in a class hierarchy) and overloading (related to a function having the same name but taking different parameters). You also have hiding of names (via explicit declaration of the same name in a nested declarative region or scope).

The C++ standard does not use the term "overwrite" except in its canonical English form (that is, to replace one value with a new value, as in the assignment x = 10 which overwrites the previous value of x).
