B.5. Summary

Because Objective-C is a strict superset of C, it’s important to have a strong understanding of the principles behind C before branching out to learn about the additions Objective-C brings to the table. This appendix offers you a firm foundation on which to start your Objective-C learning. It’s in no way a complete coverage of C-based programming, though, and many details have been left out.

It’s clear that Objective-C owes a great debt to the C programming language. With C-based knowledge, you can perform calculations, make decisions, and alter the flow of execution throughout your applications. Objective-C expands upon the C foundations with its own flavor of object-oriented extensions.
