Hi, a little Q:
typedef enum
{
NUM0 = 0,
NUM1 = 1,
NUM2 = 2,
NUM3 = 3,
} NUMBER;
NUMBER test=NUM0;
when i'm writing:
test++
i get an error, how can i do the ++ without the need to do casting like:
test=(NUMBER)(t est+1);
thanks

in C++ you could overload the operator++() function

I'm not sure there's a way to overload operators on enumeratued types...
As far as I know, there is no way to get an enum type from an enum type after incrementing - you have to explicitly cast it.
As an aside, I'm not sure you have to put the = 0, = 1, etc. in the enum values...they are defaulted to the values 0, 1, 2,..., n-1, where n is the number of values.

I'm writing a class with a method that will accept 1 of 3 items listed in an
enum. Is it possible to pass the item name without the enum name in your
calling statement?
EXAMPLE:
public enum EnumName
FirstValue = 1
SecondValue = 2
ThirdValue = 3

Regarding use of enum's, I am wondering what the cost of memory is when creating the enumeration on the calling side, and then using it on the function/method side. See example below. If I understand correctly, what is actually happening on the calling side is an instance of the enum class FavoriteSport is getting created and sent to the PrintFavorite routine with a default value of type int. Is this correct? Say I have a couple hundred uses...

So I was needing some extra power from my enums and implemented the
typesafe enum pattern.
And it got me to thinking... why should I EVER use standard enums?
There's now a nice little code snippet that I wrote today that gives me
an instant implementation of the pattern. I could easily just always
use such an implementation instead of a standard enum, so I wanted to
know what you experts all thought.
Is there a case for standard enums?

Hi there,
I'm fairly new at this, and I am having a bit of trouble wrapping my head around some concepts of enum for a project. So any help would be greatly appreciated.
Essentially I'm writing a program where i will have an enum in one of my classes. When the program is used, the user will define what actually goes inside the enum.
So for example what I mean is if the class is WorkDay....and the user defines what days of the weeks he or...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
