NAME

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:


  fedcba
  fedcba
