[ALACPP] Exceptional C++ : Problem 1 

Iterators
Difficulty: 7
The following program has at least four iterator-related problems. How many can you find? 

int main()
{
  vector<Date> e;
  copy( istream_iterator<Date>( cin ),
        istream_iterator<Date>(),
        back_inserter( e ));
  vector<Date>::iterator first =
      find( e.begin(), e.end(), "01/01/95");
  vector<Date>::iterator last =
      find( e.begin(), e.end(), "12/31/95");
  *last = "12/30/95";
  copy( first,
        last,
        ostream_iterator<Date>( cout, "\n" ));
  e.insert( --e.end(), TodaysDate());
  copy( first,
        last,
        ostream_iterator<Date>( cout, "\n" ));
}
