Hey there!
I have 2 classes such as below (defined in this order, but they can
be
reversed if needed)
class A
{
...
};
template
class B
{
...
};
I need to make friend B a class of friend A but unfortunately i can't
find the right syntax.
If i put this in class A...
friend class B;
it gives me a compile error about class B saying "class template has
already been declared as a non-class template"
If instead, i put this in class A...
friend class B<class T>;
it gives me a syntax error at the "
Does anyone know what the right syntax is? Google isn't helping much.
I think it's:
template<class> friend class B;
