cout vector

#include "stdafx.h"
#include <iostream>
#include <algorithm>
#include <functional>
#include <vector>
using namespace std;

int main()
{
    vector<vector<int>> v1 = { {1, 2}, {3, 4} };
    vector<vector<int>> v2 = { {5, 6}, {7, 8} };
    for (int i = 0; i < v1.size(); ++i)
    {
        transform(v1[i].begin(), v1[i].end(), v2[i].begin(), v1[i].begin(), plus<int>());
    }
    for (const auto& i : v1)
    {
        for (const auto& j : i)
        {
            cout << j << " ";
        }
        cout << endl;
    }
}

Is it possible to print the vectors with more succinct code? With something from algorithm for example. Thank you.
