Firstly I would request you to ask your doubts to the related topics only. You have asked a doubt related to trees on a problem related to arrays. It creates confusion on our side as TAs.

Coming to your problem , change your queue popping statements to this

p = q.front();
q.pop();

q.pop() has a void return type. To extract the front of the queue , you must use the front() function first.
