begin

Interface

SPROUT_CXX14_CONSTEXPR iterator begin() SPROUT_NOEXCEPT;

SPROUT_CONSTEXPR const_iterator begin() const SPROUT_NOEXCEPT;

Returns

iterator for the first element.

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.begin() == 1, "input first element is 1.");

Complexity

Recursive function invocations in O(1) (constant) depth.
