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.

Debugging and Testing

Debugging and testing take an extremely important role in the pipeline of the software development process. Testing helps us to find problems while debugging fixes them. However, if we follow certain rules during the implementation stage, lots of potential defects can be prevented. Additionally, since a test process is very costly, it would be great if we could automatically analyze software by using certain tools before human testing is required. Moreover, when, how, and what we should test regarding software is also important.

In this chapter, we will cover the following topics:

  • Understanding the root cause of an issue
  • Debugging C++ programs
  • Understanding static and dynamic analysis
  • Exploring unit testing, TDD, and BDD

Throughout this chapter, we will learn how to analyze a software defect, how to use a GNU Debugger (GDB) tool to debug a program, and...
