Re: [Dev-C++] using FLAGS

enum {
    FLAG_A =3D 0x0001,
    FLAG_B =3D 0x0002,
    FLAG_C =3D 0x0004
};

unsigned flags =3D FLAG_A|FLAG_B;

=2E..

// A is set
if (flags & FLAG_A) {}

// A isn't set
if (!(flags & FLAG_A) {}

// Only A is set
if (flags =3D=3D FLAG_A) {}

// Both A and B is set
if ((flags & FLAG_A|FLAG_B) =3D=3D (FLAG_A|FLAG_B)) {}

// A is set but not B
if ((flags & FLAG_A|FLAG_B) =3D=3D FLAG_A) {}
