Question

class Base
{
Base* next;
}

class Class1 : Base
{
}

Base* pBase = new Base();
Class1* pTest = new Class1();
pBase->next = pTest;

Class1* pClass1;
pClass1 = (Class1*)pBase->next;

I want to be able to write

pClass1 = pBase->next;

and get no compilation error C2440 (cannot convert). Or in other words I want pClass1 point to a class that pBase->next points to.

Is it possible with some operator overloading? How to do it?

Answer 1

template<class T>
class Base 
{ 
   T* next; 
} 

class Class1 : Base<Class1> 
{ 
} 

Class1* pTest1 = new Class1(); 
Class1* pTest2 = new Class1(); 
pTest1->next = pTest2;

Class1* pClass1; 
pClass1 = pTest1->next;
