Answer 1

you have not printed anything using cout ... so there is nothing to display but no output suggest that code is compiled without error

Answer 2

Captain X it should be NULL instead of Null... one more issue was there on usage of new which I mentioned with below code as comment of the statement for new

Node *head = NULL; //global variable

Node *ptr = new Node();//here also, only ptr variable is enough...you were doing ptr->
which is not correct

ptr->link=NULL;

Answer 3

Shld it show no Output?
