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

#include <iostream>
#include <vector>
using namespace std;
int main ()
{
    vector<int> myvector;
    myvector.push_back(78);
    myvector.push_back(16);
   myvector.front() += myvector.back();
    cout << myvector.front() << '\n';
    return 0;
}
