Here is my solution for Page 74 - Excercise 7 (Chapter 4). Appears to work.

The Implementation File:

Code: (Objective-C)

#import "Rectangle.h"

@implementation Rectangle

- (void) setWidth: (int) w {
	width = w;
}

- (void) setHeight: (int) h {
	height = h;
}

- (int) width{
	return width;
}

- (int) height{
	return height;
}

- (int) area {
	return width * height;
}

- (int) perimeter {
	return (width + height) * 2;
}

@end

And the Main File:

Code: (Objective-C)

#import <Foundation/Foundation.h>
#import "Rectangle.h"

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

	myRectangle = [[Rectangle alloc] init];
	
	[myRectangle setWidth: 5 ];
	[myRectangle setHeight: 6 ];
	
	NSLog(@"The rectangle is %i wide by %i high", [myRectangle width], [myRectangle height]);
	NSLog(@"Perimeter is %i and the area contained in the rectangle is %i.", [myRectangle perimeter], [myRectangle area]);

	[myRectangle release];
    [pool drain];
    return 0;
}

Good job!  No comments.
