## Detailed Description

### template\<typename \_Tp, std::size\_t \_Nm\>

struct std::array\< \_Tp, \_Nm \>"A standard container for storing a fixed size sequence of elements.

Meets the requirements of a `container`, a `reversible container`, and a `sequence`.

Sets support random access iterators.

**Template Parameters**

*Tp* Type of element. Required to be a complete type. \
 *Nm* Number of elements.
