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