Insert a Node at the Tail of a Linked List

    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;

    }
