This short book helps Objective-C developers understand C, the base language underneath Objective-C.
After finishing this book you will have a much deeper understanding of the C language and how many of its features are used to give Objective-C flexibility.
If you've ever wondered why the NSError ** parameter at the end of many Foundation APIs has two asterisks instead of one this is the book for you.
What's New in Version 1.1
Thanks everyone for the great feedback! This update includes fixes to all the reported errata.
Thanks a lot!
This is the most helpful C book for an iOS dev! Read it and finally get to understand C!
Well written "C for ObjC Programmers"
However, experienced people that have seen C before, note that the sample is the most complex this book has to offer. Recommended for entry level readers, everybody else can stop after the sample and doesn't need to buy.
Great learning opportunity!
For those who don't want to dig into the minutiae of K&R C or need a quick refresher, this book is a sterling example of cutting through the noise to help modern objective-c developers know what's truly important from one of the smartest voices in the industry!
I highly recommend checking out this book!
