Explain output of this program

#1

Please explain me this output how it is coming in the powers of 2

#2

@KetanPandey hey we are storing negative number in unsigned number, because of that the number stored in the variables will be complement so for short whose size is 16, number stored will be 2^16 - num. Similarly for others.
If this resolves your doubt mark it as resolved.

#3

Please explain how did you assume size of short as 16 as it depends on type of processor.Rest is understood

#4

@KetanPandey the sizes used are minimum sizes. And yes they can be different but this is an assumption/most common sizes.
If this resolves your doubt mark it as resolved
