请帮忙看看下面代码那里错了

#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main()
{
    string s;
    vector<string> text;
    while (cin>>s)
    {
        text.push_back(s);
    }
    for (vector<string>::iterator iter=text.begin();iter!=text.end();++iter)
    {
        cout<<*iter;
    }
    return 0;
}
