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

#include <iostream>
#include <vector>
using namespace std;
int main ()
{
    vector<int> myvector (5);
    int* p = myvector.data();
    *p = 10;
    ++p;
    *p = 20;
    p[2] = 100;
    for (unsigned i = 0; i < myvector.size(); ++i)
        cout << ' ' << myvector[i];
    return 0;
}
