Shouldn't that be string out_string(s, n);?

       // remove trailing '\0' to prevent line break        if (out_string[out_string.size()-1] = '\0')            out_string = out_string.substr(0, out_string.size()-1);

I'd use out_string.erase(out_string.size() - 1); I've no experience with iostreams though, can't help you with the real problem. Olaf
