   Classlar o’rtasida vorislikni tashkil qilish. Overriding va overloading bo’ladigan funksiyalarni yaratish
   

3.

Sana (uchta son): kun, oy,yil

Dori-darmon: nomi, ishlab chiqarilgan sanasi, ishlab chiqarish firmasi

Dori-darmon ishlab chiqarilganidan keyin necha kun o’tganligini hisoblang.

“Kompyuter” classini yarating. Maydonlari: Protsessor chastotasi (MGts), yadro soni, operativ xotira hajmi (MB), qattiq disk hajmi (GB), narxi. Ikkita virtual metod yarating: “Narx” metodida quyidagi formula orqali taxminiy narxni hisoblang: protsessor chastotasi 2000 MGts, yadro soni 2 dan kam bo’lmagan operativ xotira hajmi kamida 2048 Mb va qattiq disk hajmi 320 Gb bo’lsa, Protsessor chastotasi * yadro soni / 100 + xotira miqdori / 80 + qattiq disk hajmi / 20 formula orqali narxni($ dollar hisobida) hisoblasin. Mantiqiy tur qaytaruvchi “Yaroqlilik” nomli metod yarating. Ushbu metod Protsessor chastotasi 2000 MGts, yadro soni 2 dan kam bo’lmasa, operativ xotirasi 2048 MB dan kam bo’lmasa va qattiq disk hajmi kamida 320 GB bo’lsa rost(true), aks holda yolg’on(false) qiymat qaytarsin. Bundan tashqari, kompyuterlar haqida ma'lumotlarni chop etuvchi “Print” metodini yarating: protsessor chastotasi, yadro soni, operativ xotira hajmi, qattiq disk hajmi, narxi va ehtiyojlarimiz uchun yaroqliligi. Shuningdek, “Noutbuk” nomli avlod classini yarating. Qo’shimcha parametri - batareyaning ishlash muddati (daqiqada). Qayta yuklangan ikkita metod: “Narx” metodi oddiy kompyuterning narxiga teng miqdorga + batareya ishlash muddati daqiqalari soni * 10 ($ dollar hisobida) ga teng bo'ladi va “Yaroqlilik” metodi oddiy kompyuter shartlarini bajarganda va batareya ishlash muddati 240 daqiqadan kam bo’lmaganda rost(true), aks holda yolg’on(false) qiymat qaytarsin. Bundan tashqari, kompyuterlar haqida ma'lumotlarni chop etuvchi “Print” metodini yarating: protsessor chastotasi, yadro soni, operativ xotira hajmi, qattiq disk hajmi, narxi va ehtiyojlarimiz uchun yaroqliligi. Asosiy dasturda kompyuter va noutbuk classlarining obyektlarini yarating va ular haqidagi ma'lumotlarni namoyish qiling.
