c++ - C++中的ostream迭代器用法

这是代码

#include <iostream>
#include <string>
#include <algorithm>
#include <vector>
#include <fstream>
#include <iterator>
using std::vector;
using std::string;
using std::cout;
using std::cin;
using std::ostream_iterator;
using std::cout;

int main(){
     vector <string> me;
     string s;
     while ((cin>>s) && s!="end")
         me.push_back(s);

     std::copy(me.begin(),me.end(),
         std::ostream_iterator(cout,"\n"));



     return 0;
}

但是这里有错误

1>------ Build started: Project: stl_implementation, Configuration: Debug Win32 ------
1>  implementation.cpp

最佳答案

ostream_iterator需要模板参数；在这种情况下，请使用ostream_iterator<string>。
