Node* Insert(Node *head,int data) { struct Node *temp,*tail,*ptr; temp=new Node; temp->data=data; temp->next=NULL; if(head==NULL) { head=temp;} else { ptr=head; while(ptr!=NULL) { tail=ptr; ptr=ptr->next; } tail->next=temp; } return head;

}

bro i think you missed the struct function and above is the soln that worked for me pm me if you find any problem

Here's my solution in C++14. The class definition of SinglyLinkedListNode specifies that the constructor has an argument which is the data part of the node to be inserted.

SinglyLinkedListNode* insertNodeAtTail(SinglyLinkedListNode* head, int num){

SinglyLinkedListNode* node = new SinglyLinkedListNode(num);
node->data = num;
node->next = NULL;

if(head == NULL){
    head = node;
}

else{
    SinglyLinkedListNode* temp;
    temp = head;
    while(temp->next != NULL){
        temp = temp->next;
    }
    temp->next = node;
}

return head;

}

new_node = new SinglyLinkedListNode(data);

try this in 2nd line
