The expression: if (a & b) { ... } executes '...' if the same bit is 1 in both 'a' and 'b'. The expression c = b sets the bits in 'c' to 1, if they are 1 in 'b'.

WebApr 8, 2016 · Basically, the idea is to swap 2 bits, then 4 bits, 8 bits and 16 bits. If a integer binary representation is (abcdefgh) then what the above does is: abcdefgh — ba dc fe hg — dcba hgfe — hgfedcba The bitwise and shifting operations are fast and probably all of them can be done in registers. WebIn C the shifts work as expected on unsigned values and on positive signed values - they just shift bits. On negative values, right-shift is implementation defined (i.e. nothing can be said about what it does in general), and left-shift is simply prohibited - it produces undefined behavior. – AnT stands with Russia Jun 8, 2010 at 22:19 12
