operator[]

Interface

SPROUT_CXX14_CONSTEXPR reference operator[](size_type n);

SPROUT_CONSTEXPR const_reference operator[](size_type n) const;

Returns

The element at the specified position in the string.

Remarks

It causes undefined behavior if n is out of bounds.

Examples

#include <sprout/string.hpp>
using namespace sprout;

SPROUT_STATIC_CONSTEXPR auto input = string<8>("homuhomu");
static_assert(input[4] == 'h', "an element at position 4 is h.");

Complexity

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