Using nibbles (4 bits variables) in windows C C++ I'm programming network headers and a lot of protocols use 4 bits fields Is there a convenient type I can use to represent this information? The smallest type I've found is a BYTE I must then us
Reading Writing Nibbles (without bit fields) in C C++ Is there an easy way to read write a nibble in a byte without using bit fields? I'll always need to read both nibbles, but will need to write each nibble individually Thanks!
. net - How can you nibble (nybble) bytes in C#? - Stack Overflow I am looking to learn how to get two nibbles (high and low) from a byte using C# and how to assemble two nibbles back to a byte I am using C# and NET 4 0 if that helps with what methods can be do
C - Copying nibbles from one byte to another to generate a bitshift by . . . Note that in C char may be signed (e g maybe a signed octet with range -128 to +127); and this makes it messy to modify due to uncertainty (e g behaviour of "right shift of signed integer" isn't defined) For that reason I'd strongly recommend using unsigned char or uint8_t To write the lowest nibble you'd want to do something like:
c - how to replace given nibbles with another set of nibbles in an . . . A lot depends on how your flexible you are in accepting the "nibble list" index[4] in your case You mentioned that you can replace anywhere from 0 to 8 nibbles If you take your nibble bits as an 8-bit bitmap, rather than as a list, you can use the bitmap as a lookup in a 256-entry table, which maps from bitmap to a (fixed) mask with 1s in the nibble positions For example, for the nibble
Optimization and Methods for Reversing Nibbles of a Byte I'm currently studying encryption and I was coming up with ways of reversing the nibbles of a byte (ex 0xF5 => 0x5F) I came up with this solution: byte >> 4 | (byte 0x0F) << 4
