vector遇到的小疑点

vector遇到的小问题
#include<iostream>
#include<vector>
#include<string>
using namespace std;

int main()
{
string word;
vector< string > text;
while( cin >> word )
{
text.push_back( word );
}
cout << "words read are:" << endl;

for( vector< string >::iterator it = text.begin(); it != text.end(); ++it )
cout << *it << ' ';

cout <<endl;
return 0;
}

输入要怎么让他停下来，求教了
