"std::stringstream" unexpected behavior (simple example)

hi Guys,

i'm puzzled by the values i'm getting back from stringstream

Code:

---

#include <sstream>
#include <iostream>

int main(int argc, char* argv[])
{
    std::stringstream ss("1");
    int x;
    ss >> x;
    std::cout <<"(" <<x <<")";

    ss.str("1");
    int y;
    ss >> y;
    std::cout <<"(" <<y <<")";

    return 0;
}

---

output is!

Code:

---

(1)(-1)

---

i was of course expecting:

Code:

---

(1)(1)

---

it's causing problems in one of my programs.
anyone got an explanation?

(i'm using code::blocks with mingw if that matters)

Do a ss.clear() to clear the error state of the stringstream before using str().

thank you!
that was it. everything is working now. i didn't expect any error state in such a simple case.
