{
deque mydeck;list mylist; vector myvector;
queue first; queue second(mydeck);
queue third(second); queue > fourth(mylist);
fourth.push(10);fourth.push(11);fourth.push(12);
queue > fifth(myvector);
fifth.push(10);fifth.push(11);fifth.push(12); // Line I
while(!fifth.empty())
{
cout<fifth.pop(); // Line III
}
while (!fourth.empty())
{
cout << fourth.front() << " ";
fourth.pop(); // Line IV
}
return 0;
}
