std::basic_string_view<CharT,Traits>::rend, std::basic_string_view<CharT,Traits>::crend - cppreference.com (original) (raw)

| 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.

[edit] Parameters

(none)

[edit] Return value

const_reverse_iterator to the character following the last character.

[edit] Complexity

Constant.

[edit] Example

#include #include #include #include   int main() { std::ostream_iterator 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'; }
