Funktionales C++: generate

int gen () { static int c = 0;  return ++c; }

list<int> l (n);
generate (l.begin(), l.end(), gen);

Implementierung (in <algorithm>)

template<typename _ForwardIter, typename _Generator>
  void generate(_ForwardIter __first, 
             _ForwardIter __last, _Generator __gen)
    {
      for ( ; __first != __last; ++__first)
        *__first = __gen();
    }
