The program shape in Objective-C

The classic frame: main, an autorelease pool, and NSLog out.

// The classic shape: an autorelease pool wrapping main, NSLog out.
#import <Foundation/Foundation.h>

int main(void) {
    @autoreleasepool {
        NSString *shop = @"Spindle Records";
        NSLog(@"Opening %@", shop);
        NSLog(@"Crates on the floor: %d", 12 + 3);
    }
    return 0;
}

How it works

#import <Foundation/Foundation.h> brings the object world in.
@autoreleasepool scopes the memory of everything inside.
NSLog(@"Opening %@", shop) formats with %@ for objects.
