The bitwise AND operator (&) compares each bit of the first operand to the corresponding bit of the second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0. To keep the things simple I took only one byte ...

WebFeb 27, 2024 · Following Bitwise Operators can be used to check if a number is odd or even: 1. Using Bitwise XOR operator: The idea is to check whether the last bit of the number is set or not. If the last bit is set then the number is odd, otherwise even. WebFeb 6, 2024 · The signed shift n>>31 converts every negative number into -1 and every other into 0. When we do a -n>>31, if it is a positive number then it will return -1 as we are doing -n>>31 and the vice versa when we do for a negative number. But when we do for 0 then n>>31 and -n>>31 both returns 0, so we get a formula: 1 + (n>>31) – (-n>>31) WebApr 18, 2012 · Bitwise operators are operators (just like +, *, &&, etc.) that operate on ints and uints at the binary level.
