I don't understand the above procedure can anyone lease explain me in brief I mean how to write the values of 32 in binary form?

~ act like Not. 32 in binary 0000 0000 0010 0000. Convert to Not So 1111 1111 1101 1111. Answer in hexadecimal ffdf.

Binary representation of 32bit - 0000000000100000.
1's - 1111111111011111.
So ffdf answer.

The output is ffffffdf. in indiabix.com because its runs on 32 bit linux environment. If we run in turbo it will give ffff.
It varies from platform to platform.

Since unsigned 2 byte m = 32 can be represented as:
0000 0000 0010 0000
To do ~m means just complimenting m i.e.
~m = 1111 1111 1101 1111
In Hexa 1111 = f and 1101 = d
Therefore result is ffdf.
0000 0000 0010 0000

Assume each digit from right to left as 2 power i.
Where i =0,1,2...
Now 32 is 0000 0000 0010 0000.
Which mean 0*(2 power 0)+0*(2 power 1)+0*(2 power 2)+0*(2 power 3)+0*(2 power 4)+1*(2 power 5)+0*(2 power 6)+..

HOW TO WRITE .
32 = 0000 0000 0010 0000.
Can anyone explain this?
32 = 0000 0000 0010 0000.
Can anyone explain this?

But in the compiler provided by the indiabix.com.
The output is ffffffdf.
Can anyone explain why?
The output is ffffffdf.

How did you took m=32 as in binary: 0000 0000 0010 0000 please explain me?
