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

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
int main () 
{
    vector<int> myvector (4);
    fill (myvector.begin(), myvector.begin() + 2, 3);
    fill (myvector.begin() + 1, myvector.end() - 1, 4);
    for (vector<int> :: iterator it = myvector.begin(); it != myvector.end(); ++it)
        cout << ' ' << *it;
    return 0;
}
