istringstream не пашет

Я уже зеленею он злости.
Помогите, пожалуйста!


#include <iostream>
#include <sstream>
#include <string>
using namespace std;
int main(int argc, char *argv[])
{
string s = "this is a sample useless string";
string word;
(istringstream)(istringstream (s.substr(0,2))) >>word;
return 0;
}
