What are enum bit flags in C++?

What are enum bit flags in C++?

Enum bit flags in C++ are a way to define a set of named constants that can be combined using bitwise operations.

Can you give me an example of how to use them?

Sure! You can define an enum like this: enum Flags { None = 0, Flag1 = 1 << 0, Flag2 = 1 << 1, Flag3 = 1 << 2 }; Then combine them using the bitwise OR operator.

How do I check if a specific flag is set?

You can check if a flag is set using the bitwise AND operator. For example: if (flags & Flag1) { /* Flag1 is set */ }.

Are there any best practices for using enum bit flags?

Yes, it's best to use a separate enum for each set of flags and to define a 'None' value to represent no flags set.
