“Po’lat plita” classini yarating. Maydonlari: Plita qatlamining qalinligi (mm) va po'lat zichligi (kg / m^3) bilan ifodalanadi. Plitalar “Kvadrat” (shakli, kengligi va uzunligi bir xil beriladi, mm da), “To’rtburchak” (shakli, kengligi va uzunligi beriladi, mm da) va “Uchburchak” (shakli, to’g’ri burchakli uchburchak ko’rinishida ikkita kateti beriladi, mm da). Har bir plita uchun “Yuzasi” nomli virtual metod yozing. Shuningdek, “Og’irlik” metodini yozing, unda plitani og’irligi plita yuzasini * qalinligi * zichligi formula orqali hisoblanadi. “Ma’lumot” nomli virtual metod plitalar haqida ma’lumotni jadval ko’rinishida chop qiling. Asosiy dasturda 15 ta po'lat plitani yaratib, 5 tasi kvadrat, 7 tasi burchakli va 3 ta uchburchak shaklli bo’lib o’lchamlari tasodifiy o'lchamlar orqali yaratasiz. Plitalar haqida ma'lumotni jadval ko’rinishida chop eting. | Shakli | Kengligi | Uzunligi | Yuzasi | Og’irligi | | Uchburchak | 4 | 3 | 6 | 9kg/m^3 |
