No More Helloworlds. Build a Real C++ App: Master Real C++ Development: Architecture, Git, Testing & CMake in One Practical Workflow

Most C++ books teach the language, but not how to build real applications.

This book closes that gap.

Instead of focusing only on syntax, it shows how professional C++ development works in practice: project structure, build systems, testing, architecture, tooling, and the workflows used in real teams.

Written by a former BMW engineer who has interviewed dozens of C++ developers, this book explains what the industry expects from a C++ engineer and how to build those skills step by step.

Through a complete, end-to-end example project, you will learn how to:

• set up a professional C++ application from scratch
• use Git and CMake effectively
• organize code into clean, testable modules
• enforce architectural boundaries
• apply architecture and design patterns where they matter
• build and run unit tests with GoogleTest
• validate changes with CI before they reach the main branch
• use Docker as a reproducible build environment

If you have learned C++ but still feel unsure how to structure, build, test, and maintain a real application, this book will guide you through the entire process: from the first commit to a fully working, tested, modular project.
