WebWe will use this ability of bitwise XOR operator to toggle a bit. For example - if Least Significant Bit of j is 1, then j ^ 1 will make LSB of j to 0. And if LSB of j is 0, then j ^ 1 will toggle LSB to 1. Input number and nth bit position to toggle from user. Store it in some variable say j and n. WebAug 30, 2024 · Initially val is 0x11, its binary value is "0001 0001". In this example, we are toggling bit number 2 (i.e. third bit of the val), initially bit 2 is 0, after calling TOGGLE (val, bit) first time, the bit 2 will be 1. Hence, the value of val will be "0001 0100" – thus, the output will be 0x15 in Hexadecimal. Now, the bit 2 is 1, after calling ... 香川 21時からアイス

WebSo by our above table, this means "keep all of the bits, except for the fourth bit, as-is, and then change the fourth bit to be zero." More generally, if you want to clear a set of bits, create a number that is one everywhere you want to keep the bits unchanged and zero where you want to clear the bits. Finally, let's see why. x ^= (1u << 3) WebOct 25, 2013 · Fixed! Yes it is very much possible. Just use bitwise exclusive OR or simply XOR operator on the number with 2 to the power of n where as n is the digit you want to … WebThe XOR operator (^) can be used to toggle a bit. number ^= 1UL << n; That will toggle the nth bit of number. Checking a bit. You didn't ask for this, but I might as well add it. To check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the nth bit of number into the variable bit. tarik pukat
