Use of the XOR function.

[KVL]

Hello,

I would like to apply the XOR function on two hexadecimal values e.g.
1DABF219597B XOR 75B8F9FFA46D should be 68130BE6FD16.
I think I have to convert the values first to binary ones. Herefore I looked up
some info about the functios FBinFromHex and scanf but it's not clear to me how to use them.
Am I looking at the right direction here? Could somebody help me with these functions and
the XOR function.
Thanks a lot!!!

Assuming those are ints or longs and not char* or string values there, you can just do:
cout << 0x1DABF219597B ^ 0x68130BE6FD16;

And get the appropriate value (of course a manipulator would be needed to get that in hex format).

these are 64 bit values however. I would look into __int64 and see if that is any help. If not, you can always put this into a char buffer and xor 2 characters at a time with the use of strtol. This will work because 2 characters in hex is 8 bits. XOR does not need to know how big the value is.
