# #1,110 – The Bitwise Exclusive OR Operator

June 4, 2014 1 Comment

You can use the ^ operator to do a bitwise exclusive OR (“XOR”) operation between two integer-based values.

An exclusive OR operation is applied to two different bits, returning true if exactly one of the input bits is true. Here is a truth table showing the output value for all possible input combinations.

- 0 ^ 0 = 0
- 0 ^ 1 = 1
- 1 ^ 0 = 1
- 1 ^ 1 = 0

You can use the ^ operator on two arbitrary integer values as shown below. The operation is applied to the two integer values, one bit at a time.

int n1 = 12; int n2 = 10; int result = n1 ^ n2; Console.WriteLine("{0} ^ {1} = {2}", n1, n2, result);

It may help to use hex notation in order to better understand how the exclusive OR operation works on each bit.

int n1 = 0xC; // 12 (dec) or 1100 (bin) int n2 = 0xA; // 10 (dec) or 1010 (bin) // Result = 0110 bin (6 dec) int result = n1 ^ n2;
