Overview of this book

Despite the prevalence of higher-level languages, C++ is still running the world, from bare-metal embedded systems to distributed cloud-native systems. C++ is on the frontline whenever there is a need for a performance-sensitive tool supporting complex data structures. The language has been actively evolving for the last two decades. This book is a comprehensive guide that shows you how to implement SOLID principles and refactor legacy code using the modern features and approaches of C++, the standard library, Boost library collection, and Guidelines Support Library by Microsoft. The book begins by describing the essential elements of writing clean code and discussing object-oriented programming in C++. You’ll explore the design principles of software testing with examples of using popular unit testing frameworks such as Google Test. The book also guides you through applying automated tools for static and dynamic code analysis using Clang Tools. By the end of this book, you’ll be proficient in applying industry-approved coding practices to design clean, sustainable, and readable real-world C++ code.

Summary

As we’ve traversed the vast landscape of C++’s rich static type system, it’s worth taking a moment to reflect on how far we’ve come. From the earliest days of C++, where raw pointers and loosely typed arrays reigned supreme, to the modern era of std::optional, std::variant, and enum class, the language has evolved substantially in its approach to type safety.

The real power of these advances shines through when we consider how they improve not just individual code snippets but also entire software systems. Embracing C++’s robust type constructs can help us write safer, more readable, and ultimately, more maintainable code. Features such as the std::optional and not_null wrappers reduce the chance of null pointer errors. Advanced techniques such as template specialization and custom type traits offer unprecedented control over type behavior. These are not just academic exercises; they are practical tools for the everyday C++ programmer.
