Creating 1 byte enum 2

[ErrorLINE1CHAR1]

I need help turning the following into a 1 byte enum if possible, if its not could you please explain why not..

(
all original names have been omitted but the strings: _zz1, _zz2, _blank, none = 0xFF
)

I have already completed my program, BUT i can add a whole new section to it if i can get this into a 1 byte enum...

[purple]enum[/purple] CHARID [blue]{[/blue]

	Name1,
	Name2,
	Name3,
	Name4,
	Name5,
	Name6,
	Name7,
	Name8,
	Name9,
	_zz1,
	_zz2,
	_blank,
	Name10,
	Name11,
	Name12,
	Name13,
	None = 0xFF
};

I'm confused with how to do enum's i read a tutorial but I cant find any thing for my part where None = 0xFF (affraid that will throw a error, but i cant get this to where I need so i cant test that..)
Do I need to:

#define Name1 0
#define Name2 1
... etc


and for the 'None' do:

#define None

[purple]int[/purple] [red]0xFF[/red] = None;

instead of 'None = 0xFF' inside the enum??

Nobody can control enum type size in C++, it's an implementation defined property.

What did you want to achive in actual fact? If you want a set of short named constants, try

// use namespace CHARID (for example) to avoid names conflict
const unsigned char
  Name1 = 0,
  ...
  None  = 0xFF;

If you want some kind of type protection, define your own class CHARID with static const members and a proper interface (ctors, accessors and converters)...

Thanks ArkM, I found the source for one of my old favorite Final Fantasy games (8) and qhimm (the original auth.) had commented out that section i pasted and said

// If you can find a way to make the enum 1 byte in size, uncomment

So then i was looking up enum (yes im still a C++ n00b); now my friend is telling to use bool type..

If you guys want to have a look @ the whole file, I saved it as a txt on my server..

You can declare underlying type for enum in VC++:

enum CHARID:char { ... };

Now you have sizeof(CHARID) == 1.
But it's non-standard VC++ feature. I don't like such tricks.

thank you, I will look into this further, I have heard about "VS Dirty Tricks."

SOLVED: enum FF8CHARID : unsigned char {...

sizeof() returned 1byte!!
