WebAug 25, 2024 · Bitmask is the idea of using the binary representation of numbers to solve otherwise difficult problems. This representation is unique for each number. Example: The bits of the number 11 is “1011”, because in base 2: 11 = 8 + 2 + 1 = 1 *2³ + 0 *2² + 1 *2¹ + 1 *2⁰= “1011” When dealing with bitmask: It does not matter what the actual number is.

WebThis is similar to documenting one’s code. Knowing that this enumeration can be used as a bitmask, you can more easily determine what is going on within this developer’s code. The flags enumeration can be viewed as a single value or as one or more values combined into a single enumeration value. WebWe use bitmask operations to turn a bit on from off or vice-versa, check if a bit is on or off and for toggling a bit. Why do we use bit masking? We use bit masking to store multiple layers of values in the same set of numbers. Let us understand this with an example: consider the set S= {1,2,3,4,5,6,7}.
