The bitwise-exclusive-OR operator (^) compares each bit of its first operand to the corresponding bit of its second operand. If one bit is 0 and the other bit is 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.

Example

In the following example, the bitwise-exclusive-OR operator (^) compares the bits of two integers, nNumA and nNumB:

// Example of the bitwise-exclusive-OR operator
int nNumA=9, nNumB=3, nNumC; // 00001001, 00000011

nNumC = nNumA ^ nNumB;       // nNumC is now 10: 00001010
