How to extract all 4 hex digits from an unsigned short int?
Hi, I'd like to know how it is possible to extract all 4 digits from an unsigned short int. I have a system where I use an unsigned short int and each "hex digit" represents something. For example:
I have to extract the hex digits 1, A, 2 and B from that value, but I don't know how to do that. I know how to extract nibbles from bytes, but an unsigned short int is usually two bytes in C, so I'm clueless.Code:0x1A2B
I appreciate your help!
There are a number of ways to do this. It really just depends on how you want them split up.
You can use bitwise operators: Cprogramming.com FAQ > Bit shifting and bitwise operations
You could turn it into a string:Pick one, post your attempt and what problems you are having, and we'll push you in the right direction.Code:printf( "%x", 0x1a2b );
Quzah.
Hope is the first step on the road to disappointment.
Thanks, I'll try some bitwise operations and see what I can do with them.
