Review title: Received sooner than expected Product review: Received the DVDs much sooner than expected - in 9 days rather than 1 month as indicated - and the defect of lack of narration has been solved. To my pleasant surprise, I'm able to play the DVDs on both my notebook and code 3 DVD player.However, I give it a 4-star rating as I discovered a minor crack on the corner of one of the DVD casings but it's just a minor shipment defect, which I have no problem about it.

Review title: It's a bloated book with skeleton information Product review: The size of the book is deceiving. Firstly, half of the book is about C++. As for information on C, it contains very little information advanced pointer and array usage; the fundamental power of C. After reading the book once, there very little use of later. As a real-time software engineer, I'd strongly recommend not to buy this book.
