Summary

This chapter has been a lot of words about a very small program. If you’ve followed along and worked through HelloObjectiveC using Xcode, you should now have the skills to build and run a non-GUI Objective-C program. You can put those skills to use doing the exercises in the remainder of the book.

This chapter concludes Part I of the book: a review of C and an introduction to Objective-C. The next section is a more detailed treatment of the Objective-C language. It begins with Chapter 5, which covers method names and declarations, message expressions, and how the Objective-C messaging system works.
