      [modifier]Mise en œuvre possible

      template<class ForwardIt> ForwardIt next(ForwardIt it, typenamestd::iterator_traits<ForwardIt>::difference_type n =1){std::advance(it, n);return it;}

      [modifier]Exemple

      #include <iostream>#include <iterator>#include <vector>   int main(){std::vector<int> v{3, 1, 4};   auto it = v.begin();   auto nx = std::next(it, 2);   std::cout<<*it <<' '<<*nx <<'\n';}

      Résultat :
