If int a=5; then what is the value of (~a)

Answer 1

It flips all the bits.
5 = 0101
~5 = 1010

I am also not sure if it is 1's compliment or 2's compliment but that's how it works. ☺️

Answer 2

Thanks everyone 😃

Answer 3

Most significant bit? Or 1's complement?

Answer 4

Yeah..but if u code then output is -6...how's that?

Answer 5

To understand it you need to know 2's complement.

In short ~n = -(n+1)
~5 = -(5+1) = -6
