XULОSA
Xulosa qilib shuni aytish mumkinki,c++ dasturlash tilida tenglamalar sistemasini yechishda bir nechta uslubiyatlar ko’rsatib o’tildi. Masalan: o’rniga qo’yish uslubiyati, Gauss Jordan,Kramer,matritsa uslubiyati ko’rsatib o’tildi.
c++ tilining grafik imkoniyatlariga oid misollar yechildi. Funksiyalarni qo’llash bo’yicha bilim, ko’nikma va malakalarni shakllantirildi.
