Question

Given the following code, assume the myQueue object is a queue that can hold integers and that value is an int variable. 1 myQueue.enqueue(0);
2 myQueue.enqueue(1);
3 myQueue.enqueue(2);
4 myQueue.dequeue(value);
5 myQueue.dequeue(value);
6 myQueue.dequeue(value);
7 cout << value << endl;
