WebAug 5, 1998 · In C (and C++) the XOR operator is ‘^’, so ‘a ^ b’ will do a bit-wise XOR operation between a and b and return the result. There is also a XOR-assignment operator ‘^=’, so ‘a ^= b’ will do a bit-wise XOR of b ont a, replacing the original value of a. Now comes some magic, we can use XOR’s bit state swapping abilities to do WebIn the context of computer science, a mask, or bitmask, can be used to clear one or more bits to 0, set one or more bits to 1, or invert one or more bits as required. We’ve already seen an example of masking when we used the ^ …

WebApr 5, 2024 · The bitwise NOT ( ~) operator returns a number or BigInt whose binary representation has a 1 in each bit position for which the corresponding bit of the operand is 0, and a 0 otherwise. Try it Syntax ~x Description The ~ operator is overloaded for two types of operands: number and BigInt. For numbers, the operator returns a 32-bit integer. WebJan 25, 2016 · Flipping a bit means toggling or inverting the current bit status. If the current bit is set i.e. 1 than invert it to 0 and vice versa. To flip all bits of a binary number you can run loop from 0 to size of the integer and flip individual bit at a time. However, C language has given bitwise complement ~ operator for the purpose.

WebXORreturns 1if and only ifan odd numberof bits are 1. Therefore, if two corresponding bits are 1, the result will be a 0, but if only one of them is 1, the result will be 1. Therefore inversion of the values of bits is done by XORing them with a 1. If the original bit was 1, it returns 1 XOR 1 = 0. If the original bit was 0it returns 0 XOR 1 = 1.
