What real life applications do bitwise operators have?

Question

I recently learned about the bitwise operators &, |, <<, >>, and ^.

Unless if we're using && or || for if statements, I haven't seen these be used in actual coding.

I was wondering if learning these have any actually useful applications in real world programming.

Answer 1

i've used them in competitive programming sometimes. ..for example
if you have a number n=7
by doing
n=n <<1; in c++ or c
it's equal to multiply the number by 2

and by using the bitwise operation you are able to see if a number is power of 2 or to calculate what is the nearest power of 2 in not many lines

Answer 2

ok i made the same exaple i told you in words
Ps: insert a number when you run it
