NAME¶

std::basic_string_view::rend,std::basic_string_view::crend - std::basic_string_view::rend,std::basic_string_view::crend

Synopsis¶

constexpr const_reverse_iterator rend() const noexcept; (since C++17)
constexpr const_reverse_iterator crend() const noexcept; (since C++17)

Returns a reverse iterator to the character following the last character of the
reversed view. It corresponds to the character preceding the first character of the
non-reversed view. This character acts as a placeholder, attempting to access it
results in undefined behavior.

Parameters¶

(none)

Return value¶

const_reverse_iterator to the character following the last character.

Complexity¶

Constant.

Example¶

// Run this code

#include <algorithm>
#include <iostream>
#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(), str_view.rend(), out_it);
*out_it = '\n';

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

Output:¶
