Accesses the static type of the elements in an array object as if it was a tuple.
This class specialization simply provides a member type, which aliases T, as if defined as:

Tuple element type for array
This class specialization simply provides a member type, which aliases T, as if defined as:
|

See tuple_element for more information.
Template parameters
- I
- Order number of the element within the array (zero-based).
All elements in an array object have the same static type, and thus this is not relevant for this specialization. But a program is ill-formed if I>=N.
size_t is an unsigned integral type. - Tpl
- Tuple-like type: array<T,N>.
- T
- Type of the elements contained.
Aliased as member type. - N
- Size of the array, in terms of number of elements.
Member types
| member type | definition |
|---|---|
| type | T (the type of the elements contained in the array). |
