What is the uses and benefits of bitwise operator...?

Question

I am really confused about bitwise operators....is it necessary to use them...

Answer 1

They are usually faster and sometimes more convient to use.
However, except for "not" operations, I think you wouldn't really need them.

For example dividing a number by some power of two can take a lot of clock cycles since divison is an expensive operation.
Shifting the bits by this power yields the same result but is a lot faster, since you directly change the bit representation of that number.

Answer 2

you can use it eg for bitmap graphics operations too, or for manipulating with numbers in relation to hardware representation of numbers
