继承与多态性 [英] Inheritance & polymorphism

问题描述

大家好，


我只是想知道，在Java中有一个名为instanceOf的运算符，

在c ++中是等价的吗？


先谢谢所有人。

提前致谢对所有人来说。

最接近的等价物是dynamic_cast（指针变体），但是它/ b $ b类似于C＃'s"超过它的实例。

还有另一种方法，然后是dynamic_cast吗？

Hi all,

I was just wondering, in Java there is an operator called instanceOf,
whats the equivalent in c++?

Thanks in advance to all.

The closest equivalent is dynamic_cast (the pointer variant), but it
resembles C#''s "as" more than it does instanceof.

is there another way then a dynamic_cast ?
