Give two use of bitwise and (&) operator?
Give two use of bitwise and (&) operator?
It can be used to check
whether particular bit is set or not. Eg suppose we have a number 101. Now if
we want to check whether its second bit is on or off. To know this we must
simply do bitwise and operation on this number with 010. Since result is 0
therefore we can acknowledge that second bit is low in our case.
It
can be used to unset particular bit. Eg if you want to unset second LSB of any
number then you must simply do bitwise operation between that number and
…11111101.
