Bu dasturda, "Shape" sinfi doirasida "Rectangle" va "Circle" sinflari yaratilgan. "Area" funksiyasi ularning hamma sinflari uchun virtual e'tibor qilinadi. "Rectangle" va "Circle" sinflarida esa "Area" funksiyasining mos ravishda qayta yozilishi (override kalit so'zi bilan) va ushbu sinflarga xos yuzalarni hisoblash imkoniyati berilgan.
