NSArray *initializedNSArray = [NSArray arrayWithObjects: @"red", 
                                                         @"blue", 
                                                         @"green", 
                                                         @"yellow", 
                                                         nil]
for( int i=0; i<4; ++i )
    NSLog(@"%@ is a color \n", [initializedNSArray objectAtIndex: i];
                             // ^^^^^^^^^^^^^^^^^  to array it is earlier initialized to
