Thankyou Andrew.S

I mistakenly did 'template <typename T> C<T>::C {};' and got mislead.

However, i still get an error (gnu c++ -std=c++20):

-----------------------------

template<typename T> struct C {
     C();
};

template<typename T> C<T>::C(); <-- error: declaration of ‘C<T>::C()’ outside
of class is not definition [-fpermissive]

-----------------------------
