Answer 1

class List{


public:


	int item;


	int pos;


	List* nextNode;
	//destructor 
	~List(){
		if(nextNode!=NULL){
			delete nextNode;
		}
		
	}


	List()


	{


		this->pos=0;


	}


	List(int pos)


	{
		nextNode=NULL;
		this->pos=pos;


	}


	List(int item,int pos)


	{
		nextNode=NULL;
		this->item=item;


		this->pos=pos;


	}


	List(List &list)


	{
		nextNode=NULL;
		this->item=list.item;


		this->pos=list.pos;


		this->nextNode=list.nextNode;


	}


};
