# Standard library header <dynarray>

From cppreference.com
< cpp‎ | header

This header is part of the containers library.

### Includes
`<initializer_list>`
### Classes
dynarray (since C++14) | fixed-size contiguous array (class template) [edit]
std::uses_allocator<std::dynarray> (C++11) | specializes the std::uses_allocator type trait (function template) [edit]
### Functions
operator==operator!=operator<operator<=operator>operator>= | lexicographically compares the values in the dynarray (function template) [edit]

### [edit] Synopsis

    namespace std {

        template <class T> class dynarray;

        template <class Type, class Alloc>
        struct uses_allocator<dynarray<Type>, Alloc>;

        template <class T>
        bool operator==(const dynarray<T>& x, const dynarray<T>& y);
        template <class T>
        bool operator!=(const dynarray<T>& x, const dynarray<T>& y);

        template <class T>
        bool operator<(const dynarray<T>& x, const dynarray<T>& y);
        template <class T>
        bool operator>(const dynarray<T>& x, const dynarray<T>& y);
        template <class T>
        bool operator>=(const dynarray<T>& x, const dynarray<T>& y);
        template <class T>
        bool operator<=(const dynarray<T>& x, const dynarray<T>& y);
