constexpr const_iterator end()constnoexcept;		(since C++17)
constexpr const_iterator cend()constnoexcept;		(since C++17)

Returns an iterator to the character following the last character of the view. This character acts as a placeholder, attempting to access it results in undefined behavior.

Parameters

(none)

Return value

const_iterator to the character following the last character.

Complexity

Constant.

Example

Run this code

#include <iostream>#include <iterator>#include <string_view>   int main(){constexprstd::string_view str_view("abcd");constexprauto end = str_view.end();constexprauto cend = str_view.cend();   static_assert (*std::prev(end)=='d'&&'d'==*std::prev(cend) and end == cend );}
