Example
// list::pop_front
#include <iostream>
#include <list>
using namespace std;
int main ()
{
list<int> mylist;
int sum (0);
mylist.push_back (100);
mylist.push_back (200);
mylist.push_back (300);
cout << "Popping out the elements in mylist:";
while (!mylist.empty())
{
cout << " " << mylist.front();
mylist.pop_front();
}
cout << "\nFinal size of mylist is " << int(mylist.size()) << endl;
return 0;
}
