Type safe enum bit flags

Question

I\'m looking to use a set of bit flags for my current issue. These flags are (nicely) defined as part of an enum, however I understand that when you OR

Answer 1

If you think about type safety, it is better to use std::bitset

enum BITS { A, B, C, D }; 
std::bitset<4> bset, bset1;
bset.set(A); bset.set(C);
bset1[B] = 1;
assert(bset[A] == bset[C]);
assert(bset[A] != bset[B]);
assert(bset1 != bset);
