When operating on a bitvector, you apply a bitwise operator with a mask to isolate the bits of interest. Bitwise operators are used to test, set, and clear individual bits and perform simple set operations. These are classic bitwise code idioms worth knowing!

WebConditional Assignments vs. Bitwise Operations. One of the most frequently-used techniques in branchless programming is replacing conditional assignments with bitwise operations. Bitwise operations directly manipulate the bits that represent the data in a computer’s memory, making them very efficient and suitable for performance-critical code. WebIntroduction.
