三、“异或”运算符(^)
也称XOR运算符。
1、运算规则
若参加运算的两个二进位同号，则结果为0（假）；异号则为1（真），即：
0^0=0，0^1=1，1^0=1，1^1=0.
2、用途

Redefining NULL
... trick is to hack the compiler so that pointer<->integer conversions XOR a specific value that is an invalid pointer and still trivial enough that the target architecture can do that cheaply (usually, that would be a value with a single bit set, such as 0x20000000).

What does the [Flags] Enum Attribute mean in C#?
...
If you want to exclude a flag from the enumeration, use xor, which is ^ in C#. So if you have myProperties.AllowedColors = MyColor.Red | MyColor.Green | MyColor.Blue;. You can do: myProperties.AllowedColors = myProperties.AllowedColors ^ MyColor.Blue //myProperties.AllowedColors =...
hash function for string
...ay to do that is to rotate the current result by some number of bits, then XOR the current hash code with the current byte. Repeat until you reach the end of the string. Note that you generally do not want the rotation to be an even multiple of the byte size either.
For example, assuming the common...

Hash function that produces short hashes?
...t, like MD5 (128 bits) or SHA1 (160). Then you can shorten that further by XORing sections of the digest with other sections. This will increase the chance of collisions, but not as bad as simply truncating the digest.
Also, you could include the length of the original data as part of the result to...

`testl` eax against eax?
...rom the same bag of tricks that holds the idea of clearing a register with XOR EAX,EAX (which i saw on someone's license plate in Colorado!) rather than the obvious but maybe slower MOV EAX, #0 (i use an older notation).
