Stylistic choices

I tend to prefer to use namespaces filled with constants, rather than using enums in most cases. For example using

namespace Element {
const uint8_t No_Element = 0;
const uint8_t Air = 1;
const uint8_t Water = 2;
const uint8_t Earth = 3;
const uint8_t Fire = 4;
};

instead of


enum Element {
No_Element, Air, Water, Earth, Fire
};

Is this bad practice?

Yes. See below for a better enterprice programming practice:


namespace Error {
    enum Category {
        no_error
    };
}

int main()
{
    return Error::no_error;
}
