templated operator assignment overload not getting called

I hope this helps . X b = a; is initialization, not assignment, so the copy constructor is called.
This syntax is called copy initialization. It's similar to X b(a).
X<int> b;
b = a;
X& operator=(const X&)
{
   //...
   return this;
}

overload method not getting called in cast operator overload

wish of those help Your helper function returns Base by value, which slices off any derived-ness of the object you created inside the function, causing the virtual method to call the base version.
EDIT: I saw this had been marked duplicate but the duplicate, while explaining the problem, doesn't seem to clearly provide a nice solution to this specific problem.

What wrong with this overload of the operator+?
