Summary
This chapter introduced parallel algorithms within the STL. We began by acquainting ourselves with the <execution> header introduced in C++17, which has been pivotal in enabling parallelism in STL algorithms. This addition allows us to specify execution policies such as std::execution::seq, std::execution::par, and std::execution::par_unseq, thereby dictating the execution mode of STL algorithms.
We progressed to implementing these execution policies in standard algorithms, demonstrating the simplicity of transitioning from sequential to parallel execution. This was exemplified by adapting algorithms such as std::sort and std::for_each to run in parallel, thus harnessing the computational power of multiple cores.
The chapter then focused on the constexpr specifier and its profound impact on STL algorithms and containers. We explored the evolution of constexpr from C++11 through C++20 and its role in enabling compile-time computations for algorithms such as std:...
