About the Book
Most C++ books teach syntax, language features, or isolated techniques.
But knowing C++ is not the same as knowing how to build real C++ software.
No More Helloworlds is about that transition.
The book follows the development of one complete application and shows how professional C++ development works when all the pieces have to fit together:
- software architecture and clear module boundaries
- modern CMake and project structure
- automated testing and testable design
- Git and continuous integration
- resource management and maintainable C++ code
- Docker and reproducible development environments
- Qt and the integration of application layers
Instead of treating these topics as separate chapters from separate worlds, the book shows how they influence each other inside one real project.
You will see how architectural decisions affect testing, how CMake can enforce project boundaries, how dependencies should be controlled, and how development tooling becomes part of the design rather than something added at the end.
This book is for developers who already know the fundamentals of C++ and want to move beyond small examples, tutorials, and “Hello World” projects.
It is especially useful if you:
- can write C++ code but are unsure how to structure a complete application
- want to understand how architecture, build systems, testing, and CI work together
- are moving from learning C++ to working on real-world projects
- mentor junior developers and want a practical resource that connects language knowledge with software engineering
By the end of the book, the goal is not simply to help you write more C++.
It is to help you think like a C++ software engineer.

About the Author
Nikolai Kutiavin
Nikolai Kutiavin is a software engineer specializing in C++ development, software architecture, build systems, testing, and professional development workflows.
He previously worked as a software engineer at BMW and has interviewed dozens of C++ developers, giving him a practical view of the skills companies expect from professional C++ engineers.
Through his blog, https://sqglobe.com/, and his newsletter, From Complexity to Essence in C++, Nikolai writes about C++, CMake, architecture, testing, Git, and the engineering practices behind maintainable software.
He wrote No More Helloworlds to bridge the gap between learning C++ syntax and building complete applications. His goal is to explain not only individual tools and language features, but also how they fit together in a real development workflow.

Nikolai Kutiavin's "No More Helloworlds: Build a Real C++ App" follows the development of a small application, from initial design through implementation, testing, and CI. It is aimed at developers who know C++ but have not yet built and maintained a complete project. I read it mainly as something I...
David CermakIt's a nice book for someone who has gone through the initial phase of learning the syntax and some important fundamentals of C++. And wants something that could help in navigating how to build an application. Lot of standard books cover the best practices or software design fundamentals, that onl...
AnonymousThis book -No More HelloWorlds- has been a valuable resource for mentoring interns and junior developers. It goes beyond C++ fundamentals to cover architecture, tools, and development processes, guiding readers step by step toward building a real application. For me, it fills a long-standing gap: a ...
Ali JafarabadiThis book has taught me alot of things (cmake, docker, architecture, git etc) to build scalable C++ applications. Am grateful that this book exists. This book is really beginner friendly.
James MkangalaI have been learning C++ the wrong way for a while now (Learning Syntax and jumping from one C++ function to another) but my life changed as soon as i saw just the tittle of this book, i was curious about this book just from its tittle, and i finally got a copy, actually what i expected i even got m...
Maimo HarrisThis book has an amazing practical point of view that helps you develop any project with well established bases and industry standards. Not just theory outside real world application but rather best practices for proper application development. I really like this book.
