Help me plz

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

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.

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. https://www.sololearn.com/learn/11804/?ref=app

Bit Shifting (<<, >>): Left Shift (<<) – Shifts all bits to the left, which is equivalent to multiplying the value by a power of 2. For example, 5 << 1 (shifting 5 left by 1 bit) results in 10, as it multiplies 5 by 2. Right Shift (>>) – Shifts all bits to the right, which is equivalent to dividing the value by a power of 2. For example, 10 >> 1 (shifting 10 right by 1 bit) results in 5. Bitwise Operations (&, |, ~, ^): AND (&) – Compares each bit of two numbers and returns 1 if both bits are 1, otherwise returns 0. It’s often used for masking bits. OR (|) – Compares each bit of two numbers and returns 1 if at least one of the bits is 1. It’s used for setting bits. NOT (~) – Flips all the bits of the number (0s become 1s and vice versa). XOR (^) – Compares each bit of two numbers and returns 1 if the bits are different, and 0 if they are the same. Often used for toggling bits or finding differences between numbers.

Bitwise operations are mostly used for compiler optimizations.
