Defined in header <type_traits>
template< class T >
struct add_cv;
(1) (since C++11)
template< class T >
struct add_const;
(2) (since C++11)
template< class T >
struct add_volatile;
(3) (since C++11)

Provides the member typedef type which is the same as T, except it has a cv-qualifier added (unless T is a function, a reference, or already has this cv-qualifier)

1) adds both const and volatile

2) adds const

3) adds volatile
