Logical shift c

Witryna30 lip 2024 · The logical shift is a bitwise operation that shifts all the bits of its source register by the specified number of bits and places the result into the destination register. The bits can be shifted left or right as needed. Witryna13 kwi 2024 · It is a binary operator that takes two numbers, right shifts the bits of the first operand, and the second operand decides the number of places to shift. In other words, right-shifting an integer “ a ” with an integer “ b ” denoted as ‘ (a>>b) ‘ is …
