using namespace std;
int main()
{
char iostr[80];
strstream strio(iostr, sizeof(iostr), ios::in | ios::out);
int a, b;
char str[80];
strio << "10 20 testing ";
strio >> a >> b >> str;
cout << a << " " << b << " " << str << endl;
return 0;

char iostr[80];
strstream ios(iostr, sizeof(iostr), ios::in | ios::out);
int a, b;
char str[80];
ios << "1734 534abcdefghijklmnopqrstuvwxyz";
