how to form a linked list of objects without using structures in the declaration of class. So a class object should point to an other object of the same class.
Ex
class temp
{
    int input;
   temp *next;
public:
  getvalue();
putvalue(0;
addnext(0;
};

class Data {
          int myData ;
           Data *next ;
      public :
           Data ( int data = -1 , Data *link = NULL ) : myData ( data ), next ( link ) {}
} ;

class List {
        Data *list ;
    public :
        List () : list ( NULL ) {} ;
       void AddElementToList ( int dataElementToAdd ) ;
       void DisplayList () ;                
} ;

 In     void AddElementToList ( int dataElementToAdd )
You should implement adding a new element by using Data Constructor
