• Razryadli maydonlar ixtiyoriy butun tipga tegishli bo’lishi mumkin. Razryadli maydonlar adresini olish mumkin emas. Xotirada razryadli maydonlarni joylashtirish kompilyator va apparaturaga bog’liq.
• Razryadli maydonlar yordamida razryadli massivlar hosil qilish mumkin. Yuqorida ko’rilgan son hamma bitlarini chiqarish dasturini quyidagicha yozish mumkin:
