Overview of this book

Are you an experienced C++ developer eager to take your skills to the next level? This updated edition of Expert C++ is tailored to propel you toward your goals. This book takes you on a journey of building C++ applications while exploring advanced techniques beyond object-oriented programming. Along the way, you'll get to grips with designing templates, including template metaprogramming, and delve into memory management and smart pointers. Once you have a solid grasp of these foundational concepts, you'll advance to more advanced topics such as data structures with STL containers and explore advanced data structures with C++. Additionally, the book covers essential aspects like functional programming, concurrency, and multithreading, and designing concurrent data structures. It also offers insights into designing world-ready applications, incorporating design patterns, and addressing networking and security concerns. Finally, it adds to your knowledge of debugging and testing and large-scale application design. With Expert C++ as your guide, you'll be empowered to push the boundaries of your C++ expertise and unlock new possibilities in software development.

Type traits

So far in this chapter, we can say that we have discussed only one technique of metaprogramming, which is called (as you already saw in its behavior) improved runtime performance. There is also a second approach, called improved type safety. If, with the first option, we could compute values at compile time, we can calculate the precise types required for algorithms or data structures in this section. Type features are a prime illustration of the second possibility. We can assess and alter types using a range of utilities called type traits, which are included in the Standard Library. This is also called the metaprogramming library. To use type traits, we must include the <type_traits> header:

Helper classes are the first category on the list:

  • integral_constant(C++11)
  • bool_constant(C++17)
  • true_type
  • false_type

As the root class for all C++ type traits is the std::integral constant, all standard type traits that produce values are descended...
