std::basic_string<CharT,Traits,Allocator>::end, std::basic_string<CharT,Traits,Allocator>::cend

Since C++11

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

# Declarations

iterator end();

(noexcept since C++11) (constexpr since C++20)

const_iterator end() const;

(noexcept since C++11) (constexpr since C++20)

const_iterator cend() const noexcept;

(since C++11) (constexpr since C++20)

# Return value

Iterator to the character following the last character.

# Notes

libc++ backports cend() to C++98 mode.

# Example

#include <algorithm>
#include <iostream>
#include <iterator>
#include <string>
 
int main()
{
    std::string s("Exemparl");
    std::next_permutation(s.begin(), s.end());
 
    std::string c;
    std::copy(s.cbegin(), s.cend(), std::back_inserter(c));
    std::cout << c << '\n'; // "Exemplar"
}
