WebApr 10, 2024 · In an environment with an int type of 16..24 bits, (uint16_t)0xFF results in a 16-bit unsigned int. Left-shifting by an amount of bits greater than or equal to the size of the operand is undefined behaviour. In an environment with an int type of 25..32 bits, (uint16_t)0xFF results in an int. 0xFF × 2 24 is too large to hold in an int. Being a ...

"WebJun 25, 2009 · @JoshC: (cont.) And in C, the bit shift operators are defined in a way that abstracts them even more: they are defined in terms of the values they produce, not in terms of the way they move the underlying bits around (so if you're on some obscure platform where a hardware bit-shift instruction would produce an invalid bit layout, e.g. you've … " - Bit shift operators c

WebAssuming your byte1 is a byte(8bits), When you do a bitwise AND of a byte with 0xFF, you are getting the same byte.. So byte1 is the same as byte1 & 0xFF. Say byte1 is 01001101, then byte1 & 0xFF = 01001101 & 11111111 = 01001101 = byte1. If byte1 is of some other type say integer of 4 bytes, bitwise AND with 0xFF leaves you with least significant … WebDec 30, 2024 · As the shift does not hapen 'inplace' (byteOne = byteOne << 8), the compiler needs to use a register for the intermediate result.In the line i = (byteOne << 8) byteTwo; the size of the register for the intermediate is not specified (for example with a cast).
