Answer / vinay sachan
exclusive OR ^ is a bitwise operator known as (left assoc).
expr1 ^ expr2
ex.
0x12 ^ 0x58
returns 0x4A (the set bits in the result are those that are set in either 0x12 or 0x58, but not set in both).

Answer / rahul mathur
^ is a exclusive OR bitwise operator.
We can use this "^" operator for swaping two values without
using third variable and without using +, - operator as
shown below:
void xorSwap (int *x, int *y) {
if (x != y) {
*x ^= *y;
*y ^= *x;
*x ^= *y;
}
}
