adding elements of a vector to an unordered set

Question

Is there an easy way to add all the elements of a vector to an unordered_set? They are of the same type. Right now, I am using a for loop and was wondering if there is a better way to do it

Answer 1

If you're constructing the unordered_set then:

std::vector<int> v;
std::unordered_set<int> s(v.begin(), v.end());
