error std::ostream_iterator undeclared identifier

[h4ever]

Can you help with this error?

line 31: error C2065: 'ostream_iterator' : undeclared identifier
line 31: error C2062: type 'int' unexpected

but std::ostream_iterator<int>(file,",")
also prints error that ostream_iterator is not member of std.

stdafx.h

#include<iostream>
#include<fstream>

cpp

#include "stdafx.h"

using namespace std;

int main()
{

    vector<int> vektor(10,3);

    cout << "Original vector:" << endl;
    for(vector<int>::iterator i = vektor.begin();
        i != vektor.end(); i++)
        cout << *i << '\t';
    cout << endl;

    fill(vektor.begin(),vektor.end(),20); 
    cout << "vector has been filled with numbers 20:" << endl;
    for(vector<int>::iterator i = vektor.begin(); 
        i != vektor.end(); i++)
        cout << *i << '\t';
    cout << endl;

    fill_n(vektor.begin() + 2,5,100);

    for(vector<int>::iterator i = vektor.begin(); 
        i != vektor.end(); i++)
        cout << *i << '\t';
    cout << endl;

    ofstream file("test.txt");
    fill_n(ostream_iterator<int>(file,","), 10, 0);
    file << endl;
	_getch();
    return 0;
