WebDec 13, 2024 · Rotate Bits Try It! Example: Let n is stored using 8 bits. Left rotation of n = 11100101 by 3 makes n = 00101111 (Left shifted by 3 and first 3 bits are put back in last ). If n is stored using 16 bits or 32 bits then left rotation of n (000…11100101) becomes 00..00 11100101 000. WebJan 24, 2024 · The bitwise NOT operator (~) is perhaps the easiest to understand of all the bitwise operators. It simply flips each bit from a 0 to a 1, or vice versa. Note that the result of a bitwise NOT is dependent on what size your data type is. Flipping 4 bits: ~0100 is 1011 Flipping 8 bits: ~0000 0100 is 1111 1011
