What this book covers

Chapter 1, A Brief Introduction to C++, introduces some important properties of C++ such as zero-cost abstractions, value semantics, const correctness, explicit ownership, and error handling. It also discusses the drawbacks of C++.

Chapter 2, Modern C++ Concepts, outlines automatic type deduction using auto, lambda functions, move semantics, std::optional, and std::any.

Chapter 3, Measuring Performance, discusses asymptotic complexity and big O notation, practical performance testing, and how to profile your code to find hotspots.

Chapter 4, Data Structures, takes you through the importance of structuring the data so that it can be accessed quickly. STL containers such as std::vector, std::list, std::unordered_map, and std::priority_queue are introduced. Finally, we describe how to iterate over parallel arrays.

Chapter 5, A Deeper Look at Iterators, dives into the concept of iterators, and shows how iterators can go beyond just referring to objects in containers.

Chapter 6, STL Algorithms and Beyond, shows the obvious, and the not so obvious, advantages of STL algorithms over hand rolled for loops. It also takes a look at the limitations of STL algorithms and how the new Ranges library overcomes these limits.

Chapter 7, Memory Management, focuses on safe and efficient memory management. This includes memory ownership, RAII, smart pointers, stack memory, dynamic memory, and custom memory allocators.

Chapter 8, Metaprogramming and Compile-Time Evaluation, explains metaprogramming concepts such as constexpr, heterogeneous containers, type_traits, std::enable_if, and std::is_detected. It also gives practical examples of metaprogramming use cases, such as reflection.

Chapter 9, Proxy Objects and Lazy Evaluation, explores how proxy objects can be used to perform under-the-hood optimizations while preserving clean syntax. Additionally, some creative uses of operator-overloading are demonstrated.

Chapter 10, Concurrency, covers the fundamentals of concurrent programming, including parallel execution, shared memory, data races, and deadlocks. It also includes an introduction to the C++ thread support library, the atomic library, and the C++ memory model.

Chapter 11, Parallel STL, starts by showing the complexity of writing parallel algorithms. It then demonstrates how to utilize STL algorithms in a parallel context using the parallel extensions for STL and Boost Compute.
