5-Labaratoriya ishi

Massivlar. Bir o’lchovli va ko’p o’lchovli massivlarni tashkil etish.

Massivlar ustida amallar bajarish.

Ishning maqsadi: darsning nazariy qismini mustahkamlash va massivlar bilan ishlash ko’nikmalarini oshirish . Massivlar ishtirokida dasturlar tuzish ko’nikmalarini xosil qilish, o’rganilayotgan til va uning boshqaruvchi konstruksiyasi bilan tanishish.
