Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
reference at(size_type n);
|
|
|
|
SPROUT_CONSTEXPR const_reference at(size_type n) const;
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| The element at the specified position in the array.
|
|
|
|
Throws
|
|
========================================
|
|
|
|
| It throws std::out_of_range if n is out of bounds.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/array.hpp>
|
|
using namespace sprout;
|
|
|
|
SPROUT_STATIC_CONSTEXPR auto input = array<int, 10>{{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}};
|
|
static_assert(input.at(5) == 6, "an element at position 5 is 6.");
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| Recursive function invocations in *O(1)* (constant) depth.
