Hello. I'm using DMD 2.069.2. As per
http://ddili.org/ders/d.en/enum.html the following code is
supposed to output the *names* of the suits:
import std.stdio;
void main()
{
enum Suit { spades, hearts, diamonds, clubs }
foreach (suit; Suit.min .. Suit.max + 1) { writefln("%s",
suit); }
}
But I'm getting 0 1 2 3. Kindly advise.
You should rather use std.traits.EnumMembers to iterate the
members of an enum:
~~~~~~~~~~~~
import std.stdio;
void main(string[] args)
{
import std.traits: EnumMembers;
enum Suit { spades, hearts, diamonds, clubs }
foreach(member; EnumMembers!Suit)
writeln(member);
}
~~~~~~~~~~~~
it can also counts
~~~~~~~~~~~~
import std.stdio;
void main(string[] args)
{
import std.traits: EnumMembers;
enum Suit { spades = 23.2, hearts, diamonds, clubs }
foreach(i,member; EnumMembers!Suit)
{
writeln(member);
writeln(i);
}
}
~~~~~~~~~~~~
which is interesting to get the rank of a member, considering
that the rank is not always the same as the value (like here,
it's a float ;) ).
