WebFeb 11, 2024 · You can set clear and toggle bits using bitwise operators in C, C++, Python, and all other programming languages that support these operations. You also need to use the bitshift operator to get the bit to the right place. Setting a bit To set a bit, we'll need to use the bitwise OR operator − Example WebBitwise AND operator ( &) use to clear a bit of integral data type. “AND” of two bits is always zero if any one of them is zero. That means, 0 & 0 = 0 1 & 0 = 0 0 & 1 = 0 1 & 1 = 1 Algorithm to clear the bit: To clear the nth bit, first, you need to invert the string of bits then AND it with the number. Number &= ~(1UL << nth Position);

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. Here are some simple examples: device_reg = device_reg 0x01; // set bit 0 device_reg = device_reg & ~0x06; // clear bits 1 and 2 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 …

WebThe NOT or complement operator ( ~ ) and negative binary numbers can be confusing. ~2 = -3 because you use the formula ~x = -x - 1 The bitwise complement of a decimal number is the negation of the number minus 1.
