Bitwise operation mask

WebChanging a particular bit allows you to add or remove a member from the set. 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! WebUsing masks to change bits and test bits A mask is a bit pattern that has been defined by a programmer, which allows specific bits in a piece of data to be tested or altered. Setting …
