I am fairly new to C programming, and I encountered bit masking. What is the general concept and function of bit masking? Examples are much appreciated.
How do I use it in C++? When is it useful to use? What would be an example of a problem where a bitmask is used to see how it actually works?
14 // 1110 12 // 1100 10 // 1010 8 // 1000 When I have a larger number of actual bits in my real world scenario, this seems impractical, what is a better way using a mask to just check whether or not I meet the condit...
How can the following MakeMask function be implemented? Say I have a scoped enum that represents a set of bitflags. I want to create a consteval function that returns a bitmask of that enum. This b...
I know that you can bitmask by ANDing a value with 0. However, how can I both bitmask certain nibbles and maintain others. In other words if I have 0x000f0b7c and I wanted to mask the everything bu...
I was facing this unique problem of generating a bit-mask based on the input parameter. For example, if param = 2, then the mask will be 0x3 (11b) if param = 5, then the mask will be 0x1F (1 1111...
I have a byte (from some other vendor) where the potential bit masks are as follows: value1 = 0x01 value2 = 0x02 value3 = 0x03 value4 = 0x04 value5 = 0x05 value6 = 0x06 value7 = 0x40 value8 = 0x80...

I've had some experience in C before, however I have never seen the bitfields feature before. I know one can use bitmasks to isolate certain bits in a data structure, but why then bother with bitfi...
