The bitwise shift operators are the right-shift operator (>>), which moves the bits of shift_expression to the right, and the left-shift operator (<<), which moves the bits of shift_expression to the left. The left-shift operator causes the bits in shift-expression to be shifted to the left by the number ... WebDec 14, 2024 · Right rotation of n = 11100101 by 3 makes n = 10111100 (Right shifted by 3 and last 3 bits are put back in first ) if n is stored using 8 bits. If n is stored using 16 bits or 32 bits then right rotation of n (000…11100101) by 3 becomes 101 000..00 11100 . Please refer complete article on Rotate bits of a number for more details! 5.
