XOR on byte

How can I perform a XOR operation on 2 bytes?

example
00000110 (1st byte)
00000010 (2nd byte)

00000100 (result)

Another question is whether all files are stored in multiples of bytes?  Example, 12 bytes.  No files are stored in 12bytes 6 bits.

thanks

First question:

Try

unsigned char a,b,result;

a=(char)6;
b=(char)4;

result=a^b;

Second question:

Sure files are stored in multiples of bytes an all systems I know. DOS, Windows, OS/2, MAC, Linux. They are even stored in a large block. Almost every OS has an minimal block or cluster size, which are often a power of 2. So if your cluster size is e.g. 8192 a file which uses only 4 bytes will use 8192 bytes of your HD.
