Last item of istringstream repeats?

问题

I'm having trouble with splitting a string with sstream. It appears when the loop of cout happens, the last item of data, an integer in my case, is repeated? Is my loop set up wrong??

This is my code:

#include <iostream>
#include <string>
#include <list>
#include <fstream>
#include <sstream>

using namespace std;

int main()
{
    string inputText("Jane Smith 18");

    istringstream iss(inputText);

    while (iss)
    {
        string first;
        string last;
        int age;


        iss >> first >> last >> age;
        cout << first << " " << last <<" "<< age << endl;
    }

    system("pause");

    return 0;
}

See the picture - showing how the 'age' variable seems to be repeated. What am I doing wrong?

Thanks for your help in advance!
