add_pointer

template <class T>
struct add_pointer
{
   typedef see-below type;
};

template <class T> using add_pointer_t = typename add_pointer<T>::type; // C++11 and above

type: The same type as remove_reference<T>::type*.

The rationale for this template is that it produces the same type as decltype(&t), where t is an object of type T.

C++ Standard Reference: 8.3.1.
