C Bitwise Operators: AND, OR, XOR, Complement and Shift

In the explanations below, any indication of a bit's position is counted from the right (least significant) side, advancing left. For example, the binary value 0001 (decimal 1) has zeroes at every position but the first (i.e., the rightmost) one. The bitwise NOT, or bitwise complement, is a unary operation that performs logical negation on each bit, forming the ones' complement of the given binary … WebSep 5, 2016 · In simple terms, you use OR to set one or more bits, without affecting the others, and you use AND [with the ones-complement – the inverse – of the bit pattern] to similarly clear bits.

WebSep 7, 2024 · Bitwise operations may appear to be somewhat arcane to the uninitiated but are in fact commonly used. A prime use is in setting, clearing and testing specific bits in registers. One example involves configuring bidirectional ports for input or output mode via a data direction register, typically abbreviated DDR.

Web" Similarly, note that ORing a bit with 1 produces a 1 at the output while ORing a bit with 0 produces the original bit. " This can be used to force certain bits of a string to 1s. " For example, 0x 12345678 OR 0x0000FFF results in 0x1234FFFF (e.g. the high-order 16 bits are untouched, while the low-order 16 bits are forced to 1s). 26 WebThe City of Fawn Creek is located in the State of Kansas.
