Overview of this book

C++ has evolved over the years and the latest release – C++20 – is now available. Since C++11, C++ has been constantly enhancing the language feature set. With the new version, you’ll explore an array of features such as concepts, modules, ranges, and coroutines. This book will be your guide to learning the intricacies of the language, techniques, C++ tools, and the new features introduced in C++20, while also helping you apply these when building modern and resilient software. You’ll start by exploring the latest features of C++, and then move on to advanced techniques such as multithreading, concurrency, debugging, monitoring, and high-performance programming. The book will delve into object-oriented programming principles and the C++ Standard Template Library, and even show you how to create custom templates. After this, you’ll learn about different approaches such as test-driven development (TDD), behavior-driven development (BDD), and domain-driven design (DDD), before taking a look at the coding best practices and design patterns essential for building professional-grade applications. Toward the end of the book, you will gain useful insights into the recent C++ advancements in AI and machine learning. By the end of this C++ programming book, you’ll have gained expertise in real-world application development, including the process of designing complex software.

Understanding the root cause of an issue

In medicine, a good doctor needs to understand the difference between treating the symptoms and curing the condition. For example, giving painkillers to a patient with a broken arm will only take away the symptoms; surgery is probably the right way to help bones heal gradually.

Root Cause Analysis (RCA) is a systematic process that's used to identify the fundamental cause of a problem. With the help of associated proper tools, it tries to identify the origin of the primary cause of the problem using a specific set of steps. By doing so, we can determine the following:

  • What happened?
  • How did it happen?
  • Why did it happen?
  • What proper approach would be used to prevent or reduce it so that it never happens again?

RCA assumes that an action in one place triggers another action in another place, and so on. By tracing the action chain back...
