Assume the following code fragment is part of a complete working program. After the statements are executed, what is the output?

queue q;

int x = 5, y = 3;

q.push(8);

q.push(9);

q.push(y);

x = q.front();

q.pop;

q.push(18);

x = q.front();

q.push(22);

while (!q.empty())

{

y = q.front();

q.pop();

cout << y << " ";

}

cout << x << endl;
