WebBitwise Operators in C and C++ By Alex Allain Generally, as a programmer you don't need to concern yourself about operations at the bit level. You're free to think in bytes, or ints and doubles, or even higher level data types composed of a combination of these. But there are times when you'd like to be able to go to the level of an individual bit.

WebDec 16, 2014 · uint8_t bytes [2]; uint16_t value; value = 0x1234; bytes [0] = value >> 8; // high byte (0x12) bytes [1] = value & 0x00FF; // low byte (0x34) Above, bytes [0] starts out with the 16-bit value and shifts it right 8 bits. That turns 0x1234 in to 0x0012 (the 0x34 falls off the end) so you can set bytes [0] to 0x12.
