   N ta complex son berilgan. Ularning mavhum qismlari tasodifiy toq sonlar bilan to'ldirilsin han1da ushbu N ta coplex sonning yig'indisi topilsin.

Complex sinfidan foydalanib, ikkita kompleks sonlarni qo’shing Slice sinfidan foydalanib valarray massiv elementlari juftlari sonini aniqlang. gslice sinfidan foydalanib valarray massiv elementlarini 0 indexdan boshlab (2,5) qiymatlar sonida (2,6) qadamdagilar farqi bilan 10 ga to’ldiring.
