Bitwise operation swap
WebThe expression “data & 0xF0” gives us first four bits of data and result would be 01100000. Using bitwise right shift operator ‘>>’ , we shift the digit to the right 4 times and make the first four bits as 0. The result after the shift is 00000110. After completing the two operation we use the bitwise OR ‘ ’ operation on them. WebOct 13, 2010 · Wikipedia has an excellent explanation of the Swap-By-XOR algorithm. The formal proof that this algorithm works is a bit involved, and requires the use of the mathematical properties of binary numbers. But in simplified form, we can consider each bit of the binary value separate, since the XOR operation acts on each independently.

WebChecking bit using macro: We use the bitwise AND operator (&) to check a bit. x & (1UL << nth), it will check nth bit. To check the nth bit, shift the ‘1’ nth position toward the left and then “AND” it with the number. in the proper bit location and Anding x with the mask. It evaluates 1 if a bit is set otherwise 0.

WebNov 14, 2024 · 1. 1. 1. The bitwise AND operator is a single ampersand: . It is just a representation of AND which does its work on the bits of the operands rather than the truth value of the operands. Bitwise binary AND performs logical conjunction (shown in the table above) of the bits in each position of a number in its binary form. &.
WebThe main logic for swap the nibbles is to use the Bitwise right-shift and Bitwise Left-shift operators. Bitwise opertors are useful to do the bit level operation.

WebUse the bitwise OR operator ( ) to set a bit. number = 1UL << n; That will set the n th bit of number. n should be zero, if you want to set the 1 st bit and so on upto n-1, if you want to set the n th bit. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined ...
