back
###############################################################################
Interface
========================================
.. sourcecode:: c++
reference back();
SPROUT_CONSTEXPR const_reference back() const;
Returns
========================================
| A reference to the last element in the array.
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.back() == 10, "a last element is 10.");
Complexity
========================================
| Recursive function invocations in *O(1)* (constant) depth.
Header
========================================
| ``sprout/array/array.hpp``
| Convenience header: ``sprout/array.hpp``
