Finished questions 1 and 2 but I am not exactly sure why I am even doing the questions. This chapter is not entirely clear to me so I hope when I get to the next book on Objective-C, things will be a bit clearer. This chapter uses the <NSCopying> protocol and more specifically the copyWithZone method within the protocol. What does it do? Well, it allows you to copy an object to another object and in the process there is code to make the copy the instance variables.
Tomorrow I will do the last problem of the chapter and move on to chapter 19. Oh, by the way, I am on page 423, 44 pages to go in this book, and 18% of the way toward my overall goal!
Am thinking about getting another OOP book. The one I took out from the library did not work for me so I ordered another one. I am thinking to detour there either right after this book or right after the next Objective-C book. Not sure. whatever the case, I do not foresee me doing exercises in this OOP book. Rather, I will read it for the concepts and to also get some collateral Java under my belt. The name of the book is "Head First Object-Oriented Analysis and Design". This one seems to get good ratings so I will read a chapter or two and see where it goes.
