dynamic_cast，const_cast，reinterpret_cast。


每个

运营商都有这种限制的原因。

有谁知道每个限制的确切原因他们？

Hi,

As you know there are few operators in C++ which cant be overloaded.

They are:

.., .*, ::, ?: , new , delete , sizeof , typeid , static_casr ,
dynamic_cast , const_cast , reinterpret_cast .

Theremust be some reason for this restriction for each of the
operators.

Does anyone know the exact reason for such restriction on each of them?

推荐答案

你可以重载运算符new和delete

you can overload operators new and delete

我不认为新可以超载。 operator new可以超载

但不是新运营商。删除相同。按照任何传统书籍

进行确认。

I dont think "new" can be overloaded. "operator new" can be overloaded
but not "new" operator. Same for delete. Follow any traditional book
for confirmation.

不同之处是？


您可以拥有自己的类本地运营商new和你自己的全球性的。

And the difference is?

You can have your own class local operator new and your own global one.
