So, I'm having problems with enums.

Let's say I have this piece of code:

enum Card { NINE = 0, JACK = 2, QUEEN = 3, KING= 4, TEN = 10, ACE = 11 }
void main()
{
Card MyCard;
MyCard = NINE;
}

I get an error saying that NINE is undefined and it cannot be implicitly converted to type int. How would I make a Card variable get the value of NINE?

Try this:
> MyCard = Card.NINE;

This is because the enum declaration creates its own namespace. This is so you can disambiguate between different 'NINE' definitions...


 enum Card { NINE = 0, JACK = 2, QUEEN = 3, KING= 4, TEN = 10, ACE = 11 }
 enum Pin  { ONE = 1, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE }
 void main()
 {
 Card MyCard;
 Pin MyPins;
 MyCard = Card.NINE;
 MyPins = Pin.NINE;
 }

Use anymous enumerate,
_______________________________________________
enum{
  NINE  =  0,
  JACK  =  2,
  QUEEN =  3,
  KING  =  4,
  TEN   = 10,
  ACE   = 11
}

void main{
	auto MyCard = NINE;
}
_______________________________________________

aliases
_______________________________________________
enum Card{
  NINE  =  0,
  JACK  =  2,
  QUEEN =  3,
  KING  =  4,
  TEN   = 10,
  ACE   = 11
}

alias Card.NINE  NINE ;
alias Card.JACK  JACK ;
alias Card.QUEEN QUEEN;
alias Card.KING  KING ;
alias Card.TEN   TEN  ;
alias Card.ACE   ACE  ;

void main{
  Card MyCard = NINE;
}
_______________________________________________

or namespace Card
_______________________________________________
enum Card{
  NINE  =  0,
  JACK  =  2,
  QUEEN =  3,
  KING  =  4,
  TEN   = 10,
  ACE   = 11
}
void main{
  Card MyCard = Card.NINE;
}
