Build a Real C++ App","state","published","contactAuthorMethod","email","aboutText","

Most C++ books teach the language, but not how to build and maintain a real application.

No More Helloworlds: Build a Real C++ App closes that gap.

Instead of focusing on isolated language features, the book follows the development of a complete C++ application and shows how the different parts of professional development fit together: architecture, project structure, CMake, testing, Git, continuous integration, Docker, Qt, error handling, and resource management.

The example project is a small GUI grep-like application. It is deliberately simple enough to understand, but realistic enough to demonstrate the decisions that appear in production code.

Through the project, you will learn how to:

- split a codebase into clear architectural modules

- define and enforce module boundaries

- structure a modular CMake project

- design testable interfaces and implementations

- write unit and integration tests with GoogleTest

- use mocks without coupling tests to implementation details

- organize public and private APIs

- work with Git and pull-request-based workflows

- validate changes with continuous integration

- use Docker as a reproducible development and build environment

- integrate Qt without mixing user-interface and domain logic

- handle background work and resources safely

The goal is not to present these tools as separate topics. The goal is to show how they work together during the development of one complete application.

This book is intended for developers who already know the basics of C++ but still feel unsure how to structure, build, test, and evolve a real project.

The digital edition includes PDF and EPUB formats and may receive corrections and updates after publication.
