C ++覆盖...覆盖? [英] C++ Overriding... overwriting?
本文介绍了C ++覆盖...覆盖?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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
).
