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

In this chapter, we covered the SOLID principles, the KISS principle, constness, and immutability. Let’s see what you learned!

  • SOLID principles: SOLID is a set of five principles that help us create code that’s easy to maintain, scalable, and flexible. By understanding these principles, you’re on your way to designing code that’s a dream to work with!
  • The KISS principle: The KISS principle is all about keeping things simple. By following this principle, you’ll avoid overcomplicating your code, making it easier to maintain and debug.
  • Constness: Constness is a property in C++ that makes objects read-only. By declaring objects as const, you can ensure that their values won’t be accidentally changed, making your code more stable and predictable.
  • Immutability: Immutability is all about making sure objects can’t be changed after their creation. By making objects immutable, you can avoid sneaky bugs and make your code more predictable.

With these design principles under your belt, you’re on your way to writing code that’s both robust and reliable. Happy coding!

In the next chapter, we will try to understand what causes bad code.
