Defined in header <array>
template< std::size_t I, class T, std::size_t N > struct tuple_element<I, array<T, N> >;		(since C++11)

Provides compile-time indexed access to the type of the elements of the array using tuple-like interface

Member types

Member type	Definition
type	the type of elements of the array

Possible implementation

template<std::size_t I, typename T> struct tuple_element;   template<std::size_t I, typename T, std::size_t N> struct tuple_element<I, std::array<T,N> > { using type = T; };
