WebHá 1 dia · C++23’s New Fold Algorithms. C++20 added new versions of the standard library algorithms which take ranges as their first argument rather than iterator pairs, alongside other improvements. However, key algorithms like std::accumulate were not updated. This has been done in C++23, with the new std::ranges::fold_* family of algorithms. Web3 de ago. de 2024 · The OpenMP version of this example uses a flag to coordinate among all parallel loop iterations that the condition has been met. The version that uses the Concurrency Runtime uses the concurrency::structured_task_group::cancel method to stop the overall operation when the condition is met. C++
