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.

[edit] Parameters

(none)

[edit] Return value

Iterator to the character following the last character.

[edit] Complexity

Constant.

[edit] Notes

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

[edit] 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"
}

Output:

Exemplar
