WebAug 22, 2024 · We can construct the new value by masking the value to extract the byte and shifting it to the corresponding place, which is pretty trivial for the 16-bit values: void SwapBinary(std::uint16_t &value) { value = (value >> 8) (value << 8); } Things get a bit more complicated when we would want to process 32-bit values:
Int short, Int Byte, or other “low memory” variable types?
WebSep 27, 2024 · the intel cpu has a built in operation to do this for endian reversal purposes; I think the command is 'bswap'. If you want to do a lot of them fast. (yes, I know its not in the assignment). you can also brute force cast into unsigned char *s and swap them with the standard swap operations.. int x; unsigned char * cp = (unsigned char*) (&x); WebJul 21, 2024 · The first and second methods actually can do slightly different things. The first method reads a 32 bit value using the computer's natural byte ordering, and then swaps the bytes if bswap is true.. The second method reads a 32 bit value in little endian format (if bswap is false) or big endian format (if bswap is true).. On a little endian machine, they … nine of hearts band
