I took the opportunity to also practice iterating through arrays.

Code: (Objective-C)

#import <Foundation/Foundation.h>

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

	NSString *report1 = @"Fine in Sydney";
	NSString *report2 = @"Cloudy in Hong Kong";
	NSString *report3 = @"Fine in New York";
	NSString *report4 = @"Rain in Paris";
	NSString *report5 = @"Fine in Rio";
	
	NSArray *weatherReports = [NSArray arrayWithObjects: report1, report2, report3, report4, report5, nil];
	
	// List all locations with fine weather
	NSLog (@"FINE WEATHER AT THESE LOCATIONS:");
	for (NSString *report in weatherReports)
		if ([report hasPrefix: @"Fine"] == YES)
			NSLog (@"%@", report);

	NSLog (@"---------------------------------");
	
	// List the weather for Hong Kong only
	NSLog (@"HONG KONG WEATHER:");
	for (NSString *report in weatherReports)
		if ([report hasSuffix: @"Hong Kong"] == YES)
			NSLog (@"%@", report);
	
    [pool drain];
    return 0;
}

Looks good!  Of course, I haven't covered arrays yet in the series (that's tomorrow's--10/8--topic!).
