What do threads, atomic variables, mutexes, and conditional variables have in common? They are the basic building blocks of any concurrent application in C++, which are even for the experienced C++ programmers a big challenge.
This massively changed with C++17 and change even more with C++20/23.
What did we get with C++17, what can we hope for with C++20/23?
With C++17, most of the standard template library algorithms are available in sequential, parallel, and vectorised variants. With the upcoming standards, we can look forward to executors, transactional memory, significantly improved futures and coroutines. To make it short. These are just the highlights from the concurrent and parallel perspective.
Thus there is the hope that in the future C++ abstractions such as executors, transactional memory, futures and coroutines are used and that threads, atomic variables, mutexes and condition variables are just implementation details.
