a) C# da Nullable turlari nima uchun ishlatiladi?

C# dasturlash tilida Nullable Types — bu qiymat tiplari (masalan, 
int, bool, double kabi) uchun null qiymatni qabul qilish imkonini 
beruvchi tipdir. Oddiy qiymat tiplari odatda null qiymatga ega bo'la 
olmaydi, lekin Nullable Types yordamida bunday imkoniyatni yaratish 
mumkin.

b) Quyidagi kodning natijasi nima bo'ladi?

int? z = null;
if(z.HasValue)
{
    Console-WriteLine(z.Value):
}
else
{
    Console WriteLine("z is null");
}
Enter fullscreen mode Exit fullscreen mode

*Javob: * z is null
