While watching one of this guys CPPCon lecture for the nth time, I decided "I've bet he's written a book, I don't know what it is but I'm going to buy it." It ended up being the right book at the right time for me. The information and guidance is updated, modern, and understandable. Really elevated my understanding of software design and architecture at several levels. The book is infinitely better written than this review!

Having taken a class with Klaus in 2019, I was excited to get my hands on his book. I find Klaus to be a first-rate teacher, who has deep knowledge and can convey it well. Taking his class (which I recommend) was great, but I needed more time. This book gives me just that. His technique for teaching comes through in his writing. The book allows me to go over pieces at my pace and when necessary (for me), to review. I appreciate that design is complicated, and the book gives details about when and why you might use a particular pattern. When designing good software, a lot of your decisions are very dependent on what you’re designing and how you want to implement. Those nuances come through as each pattern is explained in detail. Finally, the book uses modern C++ standards in its examples, including C++ 20; while also including previous standards as well. I know GoF was the standard in design patterns, but for me this worked well as it is specific to C++.

This is a great book with really clear explanations of the major design patterns. It updates GoF and is much easier to understand. Thorough treatment of SOLID, value-based semantics, definition of design patterns, and performance considerations. There are really nice little examples working through the patterns. He also explains the problem of misuse of patterns, particularly since many patterns are quite similar in the implementations and it can be easy to confuse them. Well edited with few typos.

C++ Software Design is about, well, software design. This is as opposed to a lot of nitty gritty details about C++ syntax. The book really is about design, not C++ features (of course features play a role, you have to know C++). There are definitely some complex topics in the book, but in my opinion Iglberger does a good job of making them clear. Primary concepts are (there are more in the form of Guidelines): Understanding the importance of software design. Design for change. Separate interfaces to avoid artificial coupling (the Interface Segregation Principle, see the link above). Design for Testability. Design for extension (the Open Closed Principle, see the link above). Iglberger offers great high-level advice: Separate concerns Prefer composition to inheritance Prefer a non-intrusive design Prefer value semantics over reference semantics The book includes great discussions about how to use the classic Gang of Four Design Patterns, both the "old-fashioned" way with virtual hierarchies, and the "modern C++" way using value semantics. The book is friendly, conversational, and very readable for something about such a complex subject. Highly recommend.

The content of the book is great overall, however it could have been edited down by 20-30%. Many of the footnotes are not useful (most an attempt at humor), there is a lot of repetition in regards to stating what will be talked about before a section then restating it again at the end of a section. The writing style is also quite clunky as the author keeps trying to form an imaginary dialogue with the reader. I suppose I prefer the more classical, direct writing styles. Apart from the minor nitpicking, the content of the book is still great, but could have easily fit a couple more design patterns that the author wanted if the book was edited a bit better.

An idea of how to design C++ programs using the newer features.

As someone who has spent many years writing and maintaining large-scale C++ systems, I can say that C++ Software Design by Klaus Iglberger is one of the most valuable resources I’ve come across in recent years. It goes far beyond syntax or language features — it’s about thinking in C++, understanding dependencies, and crafting maintainable software architectures.Klaus doesn’t just know C++; he understands how to teach it. He takes concepts that are notoriously difficult — like decoupling, design by interfaces, or dependency management — and explains them with rare clarity and precision. His examples are practical and directly applicable to real-world projects, which makes the book not just educational but immediately useful.What I especially appreciate is that the book reflects a deep, experience-based understanding of the challenges C++ developers face today. It bridges the gap between theory and practice, showing how modern C++ supports clean design without sacrificing performance or control.If you’re serious about writing modern, maintainable, and elegant C++ code, this book is a must-read. It’s the kind of work that makes you rethink how you design systems — and helps you become a better engineer in the process.

If you’re a C++ developer in 2022, this is THE reference you need to share with your team. First release on 2022-09-21. Just wow. I find Iglberger’s approach beautifully rigorous ! Type erasure and free functions revolutionized my way of breaking dependencies. Reading the book is very pleasant, it’s like hearing him lecturing one of these great presentations he does. He has a way of ordering his arguments in a really well organized top-down manner.

Ottima trattazione dei design pattern in ambito C++. Scritto a diversi livelli di astrazione, dove molte delle considerazioni possono essere riportate anche su codebase con linguaggi differenti. Non aggiunge molto di nuovo sui vari pattern, però la trattazione è tra le più precise che si possono trovare. C'è sempre una forte discussione su quale contesto sia il migliore in ogni pattern e vengono sempre discussi i possibili contro di certe scelte di design. Ho apprezzato tanto il formalismo usato nei vari schemi delle diverse architetture presentate, molto efficace dal mio punto di vista. Lato C++ anche ci sono parecchi pattern di implementazione interessanti, che aggiungono parecchio valore al libro. Molto interessante anche come usa le ultime feature del linguaggio per ridurre le varie dipendenze dei pattern GoF classici. Quindi mi sento di consigliarlo fortemente, anche se conoscete la maggioranza dei pattern presenti nel libro, visto che molti punti di vista portati dall'autore sono veramente interessanti.

Este libro es uno de los mejores que existen para implementar los patrones de de diseño de software en C++. NO es una lectura fácil y no es para principiantes. De hecho su lectura es bastante pesada y requiere de amplios conocimientos en: características de las últimas versiones del lenguaje (C++ 20+), en programación con plantillas, y en ingeniería de software. El autor comienza mostrando las implementaciones clásicas de algunos patrones de diseño, luego explica sus limitaciones, y termina exponiendo implementaciones alternativas, principalmente utilizando plantillas y algunas cosas de C++ 20+. Si eres principiante en C++, este libro todavía no es para tí. Si eres un programador experimentado en C++, entonces te recomiendo este libro porque te hará volar la mente y verás al lenguaje de una manera completamente diferente.
