Objective-C. Array.

Objective-C is still C language. And seems like all about the common C arrays works in Objective-C. Here is a small program that generates a table of Fibonacci numbers:

#import <Foundation/Foundation.h>

#define ARRAY_SIZE 15

int main (int argc, const char * argv[]) 
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    int Fibonacci[ARRAY_SIZE], i;
    Fibonacci[0] = 0; //by definition
    Fibonacci[1] = 1;
    
    for (i = 2; i < ARRAY_SIZE; ++i) 
    {
        Fibonacci[i] = Fibonacci[i - 2] + Fibonacci[i - 1];
    }
    
    for (i = 0; i < ARRAY_SIZE; ++i)
    {
        NSLog(@"[%i] = %i", i, Fibonacci[i]);
    }
    [pool drain];
    return 0;
}

The char array is the same char array:

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    char word[] = { 'H', 'e', 'l', 'l', 'o', '\0' };
    NSLog(@"%s", word);
    [pool drain];
    return 0;
}

As you see the size of the array is not mentioned in the array declaration. The array is initialized and, because, I'm going to print it in the console, I set the last array element as 0.
