That book is more like a reference manual, written by Stroustrup, the man who created C++.

He actually says so, in his website:
This is not a good book for beginners. You are right! This book is written assuming that the reader is a programmer. It says so prominently and explicitly (at least five times). For beginners, I recommend Programming -- Principles and Practice Using C++. That book is also useful for people who have programmed a bit and want to improve their style and technique - or simply to learn modern C++. It is designed for classroom use, but written with an eye on self study.
