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.

Optimizing algorithms using traits

Instead of talking about this topic in a generic abstract way, we will use a classic optimized copy example to show the usage of type traits. Consider the standard library algorithm known as copy, shown here:

template<typename It1, typename It2>It2 copy(It1 first, It1 last, It2 out);

Obviously, we can write a generic version of copy() for any iterator types—that is, It1 and It2 here. However, as explained by the authors of the Boost library, there are some circumstances where the copy operation can be performed by memcpy(). We can use memcpy() if all of the following conditions are satisfied:

  • Both types of iterators, It1 and It2, are pointers
  • It1 and It2 must point to the same type, except for const and volatile qualifiers
  • A trivial assignment operator must be provided by the type that It1 points to

Here, the trivial assignment operator means that the type is either a scalar type or that one of the following...
