   OYD ning merosxo’rlik va polimorfizm xususiyatlaridan foydalangan holda vazifaga muvofiq dasturlar yaratish
   

“Avtomobil” classini yarating. Maydonlari: Nomi, maksimal tezligi(km/s), narx. Konstruktor orqali faqat nomi va maksimal tezligini kiriting. Ikkita virtual metod yarating: "Narx" metodi – mashina narxini quyidagi fomula bilan hisoblaydi: maksimal tezlik * 100 $(AQSH dollari hisobida) va "Modelni yangilash" metodi maksimal tezlikni 10 km/s ga oshiradi. Bundan tashqari, obyekt haqida ma'lumotlarni chop qiluvchi “Axborot” metodini yarating: Nomi, maksimal tezlik va narx. Bundan tashqari, “Zamonaviy avtomobil” nomli avlod class yarating. Maydonlarini ajdod class dan qabul qilsin. Qayta yuklangan 2 ta metodi mavjud: "Narx" metodi – mashina narxini quyidagi fomula bilan hisoblaydi: maksimal tezlik * 250 $(AQSH dollari hisobida) va "Modelni yangilash" metodi maksimal tezlikni 25 km/s ga oshiradi. Asosiy dasturda Avtomobil classidan 140 km/s maksimal tezlikka ega va Zamonaviy avtomobil avlod classidan 160 km/s maksimal tezlikka ega bo’lgan obyektlar yarating. Avtomobillar haqida ma’lumotlarni ekranga chiqaring. Avtomobillarni modellarini yangilang va qayta ma’lumotlarni chop qiling.
