Игра змейка на С++

[Duran-]

немогу сообразить как сделать хвост змейке.Может вы чем поможете?
PS:только начал изучать программирование поэтому прошу не смеяться с написанного мною.

Я когда то давно писал. У меня, кажется, у змейки голова была 1, пузо 2, пузо с едой 4, хвост 5. А добыча была 6. при этом голова влево была 11, вправо 12, вверх 13, вниз 14. Хвост 51-54. Ну и в этом духе. В зависимости от цифирь,выводил картинку. Правда циклов там было...

Змейка - динамический массив. Когда змейка движется, смещай его к концу и в первый элемент помещай новую позицию головы. Когда змейка ест, удлинняй массив.
