A good analogy is a group of people waiting in line of a ticket. The next one admitted is the person in the line who got here ahead of everyone else. Common operations of queue on C++ are bool empty() Returns True if the queue is empty, and False otherwise. T & front() Returns a reference to the value at the front of a non-empty queue.
