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

#include <iostream>
#include <iterator>
#include <list>
using namespace std;
int main () 
{
    list<int> mylist;
    for (int i = 0; i < 10; i++) 
    mylist.push_back (i * 10);
    list<int> :: iterator it = mylist.begin();
    advance (it, 5);
    cout  << *it << endl;
    return 0;
}
