void createLL(Node *&head,int a[],int n){

void Print(Node *head)

Node *temp = head;
while(temp!=NULL){
cout<data<<" ";
temp = temp->next;
}
}
why are we suppose o use reference operator in insertion of data in linkedlist while not in case of printing it??
whenever in any function, you are modifying the linked list or changing the data, you pass it by reference ie. with & operator. Here print function is not modifying nay data in the linked list so it has not been passed by reference.
