SPROUT_CXX14_CONSTEXPR 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

#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.
