在这里，我有一个关于 STL 的 pdf 的基本示例。为什么它不起作用？

#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;
}

错误：

我想知道有什么问题。这是一个 Win32 控制台应用程序。

#include <string>

这可能会有所帮助。
