Splet22. avg. 2024 · One solution to this problem, covered by the Bit Twiddling Hacks site, is called "xor-swapping" . You just xor-assign the two variables back and forth and back, and they end up swapped: # swap a, b a ^= b b ^= a a ^= b To really see why this works, I recommend doing a few examples by hand. Splet20. jan. 2024 · In this video, we learn to swap all odd and even bits of a given number using Bit Manipulation concepts in C/C++. Swapping is a useful application of bit manipulations.

SpletAll you need to do is to swap all odd position bits with even position bits. Every odd position bit is swapped with the adjacent bit on the left side and every even position bit is swapped with the adjacent bit on the right side. Print the number formed after swapping. For example: Sample Input: 15 Sample Output: 13 How? Well the answer would be:

SpletIt compares bits of two operands and returns false or 0 if they are equal and returns true or 1 if they are not equal. The truth table of XOR operator is as follows: ...
