What is masking in programming?

In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field. Using a mask, multiple bits in a byte, nibble, word etc. can be set either on, off or inverted from on to off (or vice versa) in a single bitwise operation.

Similarly, you may ask, what is masking in C programming?

Masking is the process or operation to set bit on to off or off to on in a byte,nibble or word. Mask means to block. Masking is the process by which ,only required data is retained and the rest is masked (blocked) Masking can be done using Bitwise Operators. Most Commonly Used Bitwise Operator is AND(&)

Also Know, how do Bitmasks work? Bitmasks a.k.a. lightweight, small sets of Booleans (native support in C/C++/Java). An integer is stored in a computer's memory as a sequence/string of bits. Thus, we can use integers to represent a lightweight small set of Boolean values. We know an integer is just a bunch of bits stringed together.

Similarly, it is asked, what is the purpose of bit masking?

Bit Masks. Bit masks are used to access specific bits in a byte of data. In this example the pin needs to change it's state from high to low for each bit in the byte to be transmitted. This is accomplished using what are known as bitwise operations and a bit mask.

What is a hex mask?

A mask is a binary number that can be used together with bitwise operators (&, |, and ^) to manipulate binary data. Binary data is usually expressed in hex because converting between hex and binary is very easy.
