99 Bottles of Beer on the Wall in Objective-C (thing)

Yes, here it is, the program you've been waiting for! Er, ok... I wrote this a while back and sent it to the 99 Bottles of Beer on the Wall Page, but they never put it up... Seeing as most people have no idea what Objective-C is, let alone what it looks like, this makes a pretty good sample. It could be simpler, but I wanted to do a class to at least show that part of the language.

main.m

#import <objc/Object.h>
#import "Beer.h"

main()
{
   id beer = [[Beer alloc] init]
   int i;
   for (i=99; i>0; i--) 
   {
      [beer print: i]
   }
   [beer free]
}

Beer.h

#import <objc/Object.h>

@interface Beer : Object

{
}

- init;
- print:(int)num;

@end

Beer.m

#import "Beer.h"

@implementation Beer

- init 
{
   [super init]
   return self;
}

- free
{
   return [super free]
}

- print:(int)num
{
   char *end;
   end = num != 1 ? "s" : "";
   printf("%d bottle%s of beer on the wall\n", num, end);
   printf("%d bottle%s of beer\n", num, end);
   printf("Take one down, pass it around\n");
   num--;
   if (num > 1) 
     printf("%i bottles of beer on the wall\n\n", num);
   else {
     if (num ==1)
        printf("%i bottle of beer on the wall\n\n", num);
     else
        printf("Anyone want tequilla?\n\n");
   }
   return self;
}

@end

This may even compile with gcc -o beer Beer.m main.m -lobjc -lpthread (if you have gcc built with Objective-C support)
