How to execute one function for all vector elements at the same time?

Question

C++ / C#

Yes vector<T> vec, function . I want to execute the function f for each element in vec, and store all the results in ; This can be done with a loopbool f(T)
vector<bool> res

for(auto &i: vec)
{
    res.push_back(f(i));
}

But I want to parallelize the execution of the function f for each element using C++ threads/future
The function f is pure.

Naturally, there is nothing suitable out of the box.
