stl copy（）iterator：バイナリ '>>'：演算子が見つかりません

Question

ここでは、STLのpdfの基本的な例があります。 なぜ機能しないのですか？

#include "stdafx.h" 
#include <vector> 
#include <algorithm> 
#include <iostream> 
#include <iterator> 

using namespace std; 


int _tmain(int argc, _TCHAR* argv[]) 
{ 
    vector<string> coll; 
    copy(istream_iterator<string>(cin), //start of source 
      istream_iterator<string>(), //end of source 
      back_inserter(coll)); 
    return 0; 
}

私が間違っているのだろうか。これはWin32コンソールアプリケーションです。

Answer 1

#include <string> 

これは役に立ちます。
