enum Conflicts

[thetrueaplus]

Hey.

I'm trying to make a couple of enums work, however mingW isn't
compiling it because it says the previous declaration of none
conflicts. is there a way to solve this?

namespace Namespace
{
enum Gender // m or f
{
none = 0,
male = 1 << 0,
female = 1 << 1
};

enum LookingFor
{
none = 0,
friendship = 1 << 0,
dating = 1 << 1,
relationship = 1 << 2,
randomPlay = 1 << 3,
whateverICanGet = 1 << 4
};
}

There is a plethora of ways dealing with enums, and unfortunately no
standard way everyone agrees upon.

Two popular ways are wrapping each enum in a class or namespace of
it's own:

namespace Gender
{
enum enum_t { ... };
}

or

class Gender
{
enum enum_t { ... };
};

With both approaches, you can have functions like toString that are
found by ADL.

I'd suggest you do something based on one of these approaches.

Regards,

Would you be kind to show how the boolean operators work on these?
Would it be like Gender::male?

I'm not sure what you mean by boolean operators.

Gender::male would be a way to refer to an enumerator, eg.

std::string toString(Gender ::enum_t e)
{
switch(e)
{
case Gender::male: return "male";
case Gender::female: return "male";
}

throw std::runtime_er ror("invalid enum");
}

Thanks guys. I put each of them into a namespace. So when I delcare
one I do

facebook::Gende r::Gender name;
name = facebook::Gende r::male;
