1.编码
int main(int argc, char *argv[])
{std::vector<int> array;for (int i = 1; i <= 100; ++i){array.push_back(i);}std::vector<int> result(array.size());std::transform(std::execution::par, array.begin(), array.end(), result.begin(), [](int x) {static std::mutex mutex;std::lock_guard<std::mutex> lock(mutex);std::cout << std::this_thread::get_id() << " " << x << std::endl;return x * 10;});
}
2.编译
g++ -std=c++20 main.cpp -ltbb
3.执行输出
