C++ 11 range based for loop
WebDec 2, 2014 · Meanwhile, for nearly three decades, C++ supported only C-style for loops. Finally, in C++11, range-based for loops were added: for (int x : myList) std::cout << x; You can iterate over a std::vector or any class which implements the begin and end member functions – not unlike Python’s iterator protocol. WebIf you still insist on using the C++11 syntactic sugar, and if it takes a (comparatively) lot of time to process each element of stl_container, then you could use the single-producer tasking pattern: #pragma omp parallel { #pragma omp single { for (auto x : stl_container) { #pragma omp task { // Do something with x, e.g. compute(x); } } } }
