NAME¶

std::basic_string_view::rbegin, - std::basic_string_view::rbegin,

Synopsis¶

constexpr const_reverse_iterator rbegin() const noexcept; (since C++17)
constexpr const_reverse_iterator crbegin() const noexcept; (since C++17)

Return value¶

const_reverse_iterator to the first character.

Complexity¶

#include <iterator>
#include <string_view>

int main()
{
std::ostream_iterator<char> out_it(std::cout);
std::string_view str_view("abcdef");

std::copy(str_view.rbegin(), std::next(str_view.rbegin(), 3), out_it);
*out_it = '\n';

std::copy(str_view.crbegin(), std::next(str_view.crbegin(), 3), out_it);
*out_it = '\n';
}
