WebHere is an example of how to use the bitwise AND operator in C++: The output of this program will be: x & y = 0 In this example, the bitwise AND operator is used to perform a bitwise AND operation on the x and y variables. The result is stored in the z variable, which has a value of 0 in decimal. Note that the bitwise AND operator has a higher … 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. Right rotation of n = 11100101 by 3 makes n = 10111100 (Right ...
