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.

Parameters

(none)

Return value

Iterator to the character following the last character.

Complexity

Constant.

Notes

In libstdc++, cend() is not available in 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"
}

Output:

Exemplar

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior
LWG 1192 C++98 std::basic_string did not have the member function cend() added
