<p><u>Очередь (queue)</u> - это линейная структура данных, подчиняющаяся правилу "первым пришел - первым вышел". Как видно из названия, очередь моделирует обычную ситуацию ожидания: новые люди непрерывно присоединяются к хвосту очереди, а стоящие в начале по одному уходят.</p>
<p>Как показано на рисунке 5-4, начало очереди называется "головой очереди", а конец - "хвостом очереди"; операцию добавления элемента в хвост называют "enqueue", а операцию удаления элемента из головы - "dequeue".</p>
