Assalomu aleykum Xurmatli dasturchilar.
PROGRAMMERS kanalimizda savol - javob viktorinasini olib borayapmiz. Viktorinamizda berilayotgan savollar va javobllar yuqorida qolib ketganligini hisobga olgan holatda, viktorinamizdagi savol javoblarni @programmersQuiz_bot botiga joylab borayapmiz. Botga a'zo bo'ling. Hali savollar oldida ...
Botdagi C++ bobidagi Boolean bo'limini yakunladik.

Java dasturlash tilida o'zgaruvchilarni e'lon qilishdan avval uning toifasi ko'rsatiladi.
Misol uchun:
int number;
String str;
Kotlin dasturlash tilida esa, o'zgaruvchilarni e'lon qilishdan avval val (value) yoki var (variable) yoziladi
Misol uchun:
var counter
val str
Qachon val, qachon var yozamiz?
Agar boshlang'ich berilgan qiymat dastur ishlashi davomida o'zgarmasa val, aks holda var yoziladi.
