Name

^ (bitwise XOR)

Examples
unsigned int a = 60;	// 60 = 0011 1100
unsigned int b = 13;	// 13 = 0000 1101
unsigned int c = 0;           

c = a ^ b;              // 49 = 0011 0001
Description Compares two expressions bit by bit and returns 1 for a position bit if one compared postitions is 1. Returns 0 for that position bit if both compared positions are 0 or 1. The following list shows all possible combinations:

1 ^ 0 // Evaluates 1 because the first is 1
0 ^ 1 // Evaluates 1 because the second is 1
1 ^ 1 // Evaluates 0 because both are 1
0 ^ 0 // Evaluates 0 because both are 0
Syntax
expression1 ^ expression2
Parameters
expression1 any valid expression
expression2 any valid expression
Usage Application

| (bitwise OR)
|= (bitwise OR and assign)
˜ (bitwise ones complement)
<< (bitwise bit shift left)
>> (bitwise bit shift right)
