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

d
d
true
