I have two classes: a

Код: Выделить всё

Parent

class and a

Код: Выделить всё

Child

class (inheriting from the

Код: Выделить всё

Parent

class). I would like to know if it is possible to cast/transform a

Код: Выделить всё

Child**

to a

Код: Выделить всё

Parent**

with

Код: Выделить всё

reinterpret_cast

or something else. Is such a thing possible?
Below is a minimal example. I am wondering is that code correct, or

Код: Выделить всё

Child**

to a

Код: Выделить всё

Parent**

"transformation" is not correct and should not be attempted?
NB: my question is on the conversion of the pointer of pointer, i.e., is this line correct?

Код: Выделить всё

Parent** ptrToChildPtr = reinterpret_cast(&childPtr);

I know that the pointer deletion could be done in a much simpler way. I just want to show here the conversion I want to perform, if such conversion is possible.
Many thanks in advance.

Код: Выделить всё

#include 
#include 

class Parent {
public:
Parent() {}
virtual ~Parent() {
std::cout
