Thanks ,
You said that"by creating an object of a child class, it will create a 64bit (int a + int b) for child class"
means when i create child object we have now memory for (int a + int b) , & then assign child_handle to parent_handle then why i can’t access child member through parent_handle??
I think we have memory of both variable a & b then what is the issue to get b signal through parent_handle b’coz parent_handle is a type of child_handle(parent_handle = child_handle )
