Just like Thinking in Java, this book is the reference and comes highly recommended.
Unlike some C++ books, this book is comprehensive and very easy to read. Bruce Eckel does a really good job at treating all fundamental concepts you need when writing C++ code.
The target audience is quite large, from the beginner to the advanced developer who wants to come back to the fundamentals.

If you can't get the paper copy of the book, you can still look at the HTML version of the book available on the author's web site for free: [...]

Thinking in C++ is quite different from other C++ books. It's for experienced programmers and contains a lot of useful and advanced topics. The book printing is quite disappointing though..

Observations:
- aimed at C programmers
- gradual introduction to C++

Constructive criticism:
- lacking diagrams and elegance
- detailed description of problems when using C

Bruce Eckel's book very thoroughly covers the Standard C++ programming language. It may be a little dated (my copy says (C) 2000), but I don't think the Standard has evolved since his writing.

The Good: Bruce does a terrific job going into gory detail on all aspects of this (let's just face it) complicated language. C++ has lot's of traps and ditches to offer compared to C# or Java, and if you plan to use a lot of the advanced concepts of the language, a helper like this book is almost indispensable. If you are coming from the C realm, this books is a real hit: Bruce constantly points out the subtle differences between C and C++, and also explains how C++ is a safer language than C in almost every facet. The book does a fairly decent job in going from the simpler to the more advanced concepts, though a few times he has to use constructs that will only be covered in later chapters (Bruce does point out these outlooks though appropriately). If you are really into learning a new language, the Exercises at the end of each chapter are a terrific way to learn the new concepts.

The Bad: The text within the chapters is not very well structured. If you later on try to find something, the prose form of the sections does not really help you doing that. Also, the Index is not that great either. Often times you are sent to pages that just marginally address the keyword, and the essential introduction or explanation of the keyword may not be in the index at all. My real gripe though is with the practicality of the examples. While I previously stated that the Examples by itself are a great way to learn the languate, a lot of his examples are just plain bad ideas how to code. I understand where Bruce is coming from, he tries to find examples for all the subtleties he just covered in the section. Nevertheless, he often asks for pretty bad things to be implemented. On principle, from my own personal experience a lot of the special cases of the language are hardly ever used in real life situations.

I do recommend this book, especially if you are coming from C. Just take the examples with a grain of salt. If you are a seasoned software developer, you can probably tell anyways which of the examples or techniques should not be used on the job.

this is a must have for all people that need to learn c++
even if you are novice or experience developer this is a book that you will always open and consult.
