Is there any problem with this code?

class A
{
public:
enum B {C=-1, D = 1, E=2, F = 3, G = 4};


//
//
};

I ask because I've never seen a negative enum value before.

Thanks,

Paul Epstein

In C++ enumerator values can be negative. I think the only problem will
occur if you try to use bitwise operations on them, where you can loose
the negative sign.

Doing bitwise operations on negative values, whether or not they're
enumerations, is dicey. In order to know what the result should be, you
have to know how the values are represented.
