[Solved] hexadecimal in typedef enum in C

Question

For a bit mask it helps to look at values in binary since that is the level needed for a bit mask. And each enum value typically only sets a single bit.

So the enum values would be set (in binary) to 00001, 00010, 00100, 01000, 10000, etc.

Those same values in decimal would be: 1, 2, 4, 8, 16, etc.

And in hex they would be 0x01, 0x02, 0x04, 0x08, 0x10, etc.

It’s really just a matter of preference but since hexadecimal is a power of 2, it better relates to binary than decimal does. This makes it slightly clearer that the values represent bit mask values.
