printing an enumeration .

kobi_hikri · #1 20-Jul-2005, 04:57

Given the definition :

CPP / C++ / C Code:

typedef enum {a,e,r} command_type;

What would be the appropriate way to print the enumeration itself (not the number that represents each value) ?
Is it possible without a switch ?

To answer your second question: yes, it is possible without switch, by using if-else.

Okay, not that funny. But, of course, this means that the answer to your first question is: by using some conditinoal statements, like switch or if-else.

Unfortunately, those are your choices. (As far as I know, of course.)

Some disgusting macro trickery:

Not nice, making fun of me :-(

Woah, there. It was a joke, but not to poke fun at you personally.

Ugh... but the char array example above the macro one looks a little nicer to me, although not something I'd use often, and not easily maintained.

They both do the same thing -- and the macro is used to handle the maintainance. Once you understand how it works, or if you just trust it, all you change is this part:

CPP / C++ / C Code:

/* Macro Binding */
MACRO(ALPHA, "This is a description of this element.")
MACRO(BETA,  "The next item has no description.")
MACRO(GAMMA, "")
MACRO(DELTA, "")

The text is automatically changed, etc.

Got it. I have rarely used macros, so I don't typically think in that way. Very good little technique to know, should I ever need or want to do such a thing. Fortunately, I never have.

Edit: I take that back. I have done a similar thing, but in Java and the maintenance (since there are no macros) is annoying.

I wouldn't think anything else.

I recently started using macros (again, in my neverending assembler project)
and found that they can dramatically improve program performance and sometimes even provide away to write "generic" code much faster.
