Help me plz

Question

Who can me explain the purposes, where we can use bit shifting ( << >>) and bitwise operations (&, |, ~, ^) in C

Answer 1

The purpose of bit shifting is to shift the binary values to either left or right accordingly by a specified number of positions.

The bitwise operators like & is bitwise AND it will be true when both are true otherwise false. In addition | is bitwise OR it will be true when either is true otherwise false. Furthermore ~ is bitwise Not it will be true when it is false and false when true like vice versa. In conclusion ^ is bitwise XOR where when same then false and if different true.

Answer 2

Виталий Янчик since computers conceptually work in binary, it is self-evident that we need operators that can manipulate bits.

In the Community section of Sololearn you can learn more about how and why to use the bitwise operators.

Answer 3

Bitwise operations are mostly used for compiler optimizations.
