NAME

std::basic_string_view<CharT,Traits>::end,std::basic_string_view<CharT,Traits>::cend - std::basic_string_view<CharT,Traits>::end,std::basic_string_view<CharT,Traits>::cend

Synopsis

constexpr const_iterator end() const noexcept; (since C++17)
constexpr const_iterator cend() const noexcept; (since C++17)

Example

// Run this code

  #include <iostream>
  #include <iterator>
  #include <string_view>

  int main()
  {
      std::string_view str_view("abcd");

      auto end = str_view.end();
      auto cend = str_view.cend();

      std::cout << *std::prev(end) << '\n';
      std::cout << *std::prev(cend) << '\n';

      std::cout << std::boolalpha << (end == cend) << '\n';
  }

Output:
