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

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.

# Declarations

constexpr const_iterator end() const noexcept;

(since C++17)

constexpr const_iterator cend() const noexcept;

(since C++17)

# Return value

const_iterator to the character following the last character.

# Example

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