Example code from episode.
Loops Example

#import int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int i=0; while (i!=2) { NSLog(@"%d", i); i++; } i=0; do { NSLog(@"%d", i); i++; } while (i!=3); NSArray *anArray = [NSArray arrayWithObjects:@"Apples", @"Oranges", @"Grapes", @"Bananas", nil]; for (int d=0; d<[anArray count]; d++) { NSLog(@"%@", [anArray objectAtIndex:d]); } NSString *theObject; for (theObject in anArray) { NSLog(@"For In: %@", theObject); } NSEnumerator *theEnumerator = [anArray objectEnumerator]; while (theObject = [theEnumerator nextObject]) { NSLog(@"Enumerator: %@", theObject); } [pool drain]; return 0; }

Goto Example

#import void testGoto() { NSString *theString = [NSString new]; if (1==12) { goto Error; } goto Cleanup; Error: NSLog(@"An error occurred"); goto Cleanup; Cleanup: NSLog(@"Releasing the string"); [theString release]; } int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; testGoto(); [pool drain]; return 0; }
