void printcontents (INTDEQUE  deque);

void main()

    INTDEQUE  dequetest;

    dequetest.push_back(1);
    dequetest.push_back(2);
    dequetest.push_back(3);
    printcontents (dequetest);
    dequetest.pop_back();
    printcontents (dequetest);
    dequetest.pop_back();
    printcontents (dequetest);
   }

   //function to print the contents of deque
   void printcontents (INTDEQUE  deque)
   {
       INTDEQUE::iterator pdeque;

       cout <<"The output is:"<<endl;

           for(pdeque = deque.begin();
           pdeque != deque.end();
           pdeque++)
       {
           cout << *pdeque <<endl ;
       }
   }

The output is: 1 2 3 The output is: 1 2 The output is: 1
