*a) Nullable types nima va qachon ishlatiladi? Misol keltiring: *

C# dasturlash tilida **Nullable Types** — bu qiymat tiplari uchun 
**null qiymat**ni qabul qilish imkonini beruvchi tipdir. Oddiy qiymat 
tiplari odatda `null` qiymatga ega bo'la olmaydi, lekin **Nullable 
Types** yordamida bunday imkoniyatni yaratish mumkin.
Nullable turlari odatda ma'lumotlar bazasi, foydalanuvchi interfeysi 
yoki boshqa ma'lumot manbalarida **null** qiymatni ifodalash zarur 
bo'lgan vaziyatlarda ishlatiladi.

*b) Quyidagi kodning natijasini ayting: *

 int? num = null;
 if(num.HasValue)
 {
     Console.WriteLine(num.Value);
 }
 else
 {
     Console.WriteLine("Null Value");
 }
Javob: Null Value
