(constexpr since C++20)const_iteratorcend()constnoexcept; (3)(since C++11)
(constexpr since C++20)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
libc++ backports cend() to C++98 mode.
Example
Run this code
#include<algorithm>#include<iostream>#include<iterator>#include<string>intmain(){std::strings("Exemparl");std::next_permutation(s.begin(),s.end());std::stringc;std::copy(s.cbegin(),s.cend(),std::back_inserter(c));std::cout<<c<<'\n';// "Exemplar"}Output:
