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

#include <iostream>
#include <queue>
using namespace std;
int main ()
{
    queue<int> myqueue;
    int sum (0);
    for (int i = 1; i <= 10; i++) 
        myqueue.push(i);
    while (!myqueue.empty())
    {
        sum += myqueue.front();
        myqueue.pop();
    }
    cout << sum << endl;
    return 0;
}
