CMPS 223 Data Structures and Algorithms 
             Assignment 2: List Implementation based on Link Structure

I. Purposes:

    How to use linked structures to implement a list.

II. What you are going to do:

   1. Define a Singly Linked List structures with the following two
      template classes:
   	template <class T>
	class Node {
	   public:
	      T		data;
	      Node<T>	*next;
	      Node( const T & );
	      ~Node();
	};

      template <class T>
      class LList {
        protected: 
      	  int		count;
	  Node<T>	head;
	public:

          LList( );
          ~LList();
          LList( const LList& );

          bool    empty() const;

	  // Return this for cascade calls. (obj, pos)
          LList& insert( const T & , int );

          T	erase( int );
          void    display() const;

          template<class C>
	  friend ostream& operator<<( ostream&, const DTList<C>& );

     };

III. Use and make a few changes to your main program and menu for assignment one
     to test the singly linked list implementation.

       Menu for assigment 2 should be like the following:

              +=========================================+
              | HW2 : Linked List Implemenatation       |
              +=========================================+
              | F: Create one integer and one character |
              |    list, and insert 10 random values in |
              |    each list. The value ranges of lists |
              |    0 ... 99 and 'A' .. 'Z'.             |
              +-----------------------------------------+
              | S: Show two lists.                      |
              +-----------------------------------------+
              | A: Ask for a int and a char value,      |
              |    insert the values at random poistions|
              |    of the lists.                        |
              +-----------------------------------------+
              | D: Generate a random position, and      |
              |    remove values at the positions of the|
              |    int and char lists.                  |
              +-----------------------------------------+
              | H: Show this menu.                      |
              +-----------------------------------------+
              | Q: Exit program.                        |
              +-----------------------------------------+
