Hi Mr. Kochan
On page 135 and 140 you make reference to program 7.1 when I think it should be making reference to program 7.2. program 7.1 does not contain the interface, but 7.2 does and it is there where I need to input the @property int numerator, denominator.

I was disappointed that this post did not receive a reply.  I have just finished working my way through these pages, and was similarly confused.

The poster is exactly correct regarding his first citation, the reference to Program 7.1 at the bottom of page 135.  It should read "as shown in Program 7.2:"  It is a forward, rather than a backward, pointer.

The poster is not correct in his second citation.  The reference in this case is to "Program 7.1" as it appears at the beginning of the 4th graph on p. 140.  If I understand this section correctly, the intent is to teach using compiler directives (@property and @synthesize) for the auto-generation of accessor methods.  If so, the text should read something like:
   "Now go back to Fraction.h and Fraction.m and make the changes to..."

Okay, let me try to clear this up.

Page 136, first line: Program 7.2 should be Program 7.1

All the other references to Program 7.1 (Pages 135 and 140) are now correct.

Cheers,

Steve

OK.  Thanks!  That makes sense. 

It must be a burden to respond to all this sort of stuff, Steve, but the goal is to help you improve this excellent book!

No, it's not a burden.    Smiley   The only hard part is answering previously-answered questions.  So I encourage all forum members to use Search in the tool bar at the top of the forum.

Cheers,

Steve

No, that wasn't directed towards you.   Shocked

That was a general response to your comment about it being a burden to answer all this stuff.

Cheers,

Steve

No worries.  Just many thanks.

I suspect that all of us lucky enough to find the book and to participate in this site are enormously grateful for your responsiveness.  It increases the value of the experience tremendously much.
