What will be the output of the following C++ code?

#include <iostream>
#include <iterator>
#include <vector>
using namespace std;
int main () 
{
    vector<int> myvector;
    for (int i = 1; i < 4; ++i) 
        myvector.push_back(i*10);
   ostream_iterator<int> out_it (cout,", ");
   copy ( myvector.begin(), myvector.end(), out_it );
   return 0;
}
