Laborotoriya ishi 1

Mavzu: Foydalanuvchi kutubxonalari bilan ishlash.

Ishdan maqsad: Dasturlash tili bilan tanishish, dasturlash tili imkoniyatlarini ko’rib chiqish, dasturiy muhitni o’rnatish , C++ tilini imkoniyatlari bilish, C++ tili bo’yicha dastlabki ma’lumotlarni bilish.

Topshiriq: www.algo.ubtuit.uz saytidagi 1-30 misollarni ishlash.
