How to swap nibbles in c
Web1. In this C Program, we are reading the number using ‘n’ variable and also the bit positions using ‘p’ and ‘q’ variables respectively. 2. First shift the bit in given position to right-end. This can be achieved by the code below. for p’th bit – n & (1 << p)) >> p) for q’th bit – (n & (1 << q)) >> q) 3. Next step is to ...

WebA nibble is half a byte, or 4 bits. You need to shift data to the right one nibble to move the left half to the right. You also need to shift data to the left one nibble to move the right half to the left. You need to combine those two results with a bitwise OR: Code: ? 1 data = (data shifted left 1 nibble) (data shifted right one nibble); Web19. jul 2005. · How to interchange the two nibbles of a byte without using any bitwise operator.
