Array(massiv) data structurening asosiy bloklaridan biridir. String faqat bir qator belgilar bilan tuzilganligi sababli, ularning ikkalasi ham o'xshashdir. Ko'pgina intervyu savollari ushbu toifaga kiradi.

Ushbu kartada biz array va string bilan tanishamiz. Ushbu kartani tugatgandan so'ng, siz:

  • array va dynamic array o'rtasidagi farqlarni tushunish;

  • array va dinamic arraydagi asosiy amallar bilan tanishish;

  • Ko'p o'lchovli massivlar (multidimensional arrays)ni tushunish va ikki o'lchovli massiv (two-dimensional array)dan foydalana olish;

  • String tushunchasini va qatorning turli xil xususiyatlarini tushunish;

  • Ikki nuqtali texnika(two-pointer technique)ni amaliy masalalarda qo'llay olish.
