Describes an object that controls a sequence of length N of elements of type Ty. The sequence is stored as an array of Ty, contained in the array<Ty, N> object.

template<class Ty, std::size_t N>
    class array;

Parameters

Parameter	Description
Ty	The type of an element.
N	The number of elements.

Members

Type Definition	Description
array::const_iterator	The type of a constant iterator for the controlled sequence.
array::const_pointer	The type of a constant pointer to an element.
array::const_reference	The type of a constant reference to an element.
array::const_reverse_iterator	The type of a constant reverse iterator for the controlled sequence.
array::difference_type	The type of a signed distance between two elements.
array::iterator	The type of an iterator for the controlled sequence.
array::pointer	The type of a pointer to an element.
array::reference	The type of a reference to an element.
array::reverse_iterator	The type of a reverse iterator for the controlled sequence.
array::size_type	The type of an unsigned distance between two elements.
array::value_type	The type of an element.

Member Function	Description
array::array	Constructs an array object.
array::assign	Replaces all elements.
array::at	Accesses an element at a specified position.
array::back	Accesses the last element.
array::begin	Designates the beginning of the controlled sequence.
array::cbegin	Returns a random-access const iterator to the first element in the array.
array::cend	Returns a random-access const iterator that points just beyond the end of the array.
array::crbegin	Returns a const iterator to the first element in a reversed array.
array::crend	Returns a const iterator to the end of a reversed array.
array::data	Gets the address of the first element.
array::empty	Tests whether elements are present.
array::end	Designates the end of the controlled sequence.
array::fill	Replaces all elements with a specified value.
array::front	Accesses the first element.
array::max_size	Counts the number of elements.
array::rbegin	Designates the beginning of the reversed controlled sequence.
array::rend	Designates the end of the reversed controlled sequence.
array::size	Counts the number of elements.
array::swap	Swaps the contents of two containers.

Operator	Description
array::operator=	Replaces the controlled sequence.
array::operator[]	Accesses an element at a specified position.

Remarks

The type has a default constructor array() and a default assignment operator operator=, and satisfies the requirements for an aggregate. Therefore, objects of type array<Ty, N> can be initialized by using an aggregate initializer. For example,

    array<int, 4> ai = { 1, 2, 3 };

creates the object ai that holds four integer values, initializes the first three elements to the values 1, 2, and 3, respectively, and initializes the fourth element to 0.
