Assign vector to multiset

Question

Is there any good way for assigning std::vector to std::multiset? Other than iteration of course. I see that in C++11 there is something like initializer list, maybe it can be used somehow?

@Xeo They are uncomfortable and probably it's not the fastest solution. — user1873947, Feb 13 '13 at 09:34
@R. Martinho Fernandes I mean, iteration requires more code than the solution from the answers. You can do it in some lines and you can do it in one line, thats the comfort. — user1873947, Feb 13 '13 at 09:36
If you're not "comfortable" doing the iteration yourself, then let the library do it for you, e.g. with [`std::copy`](http://en.cppreference.com/w/cpp/algorithm/copy). — Some programmer dude, Feb 13 '13 at 09:38
@user1873947 The answers use iterators and in a single line do exactly what you want. — Joseph Mansfield, Feb 13 '13 at 09:43

vector<int> v;
//fill your vector
multiset<int> m (v.begin(), v.end());

Use this:

std::vector<SOME_TYPE> a;
....
std::multiset<SOME_TYPE> ms(a.begin(), a.end());
