Insert a Node at the Tail of a Linked List

    Here is a simple function in C language, that inserts a node at the tail of the list:

    SinglyLinkedListNode* insertNodeAtTail(SinglyLinkedListNode* head, int data) {
    SinglyLinkedListNode *newNode = (SinglyLinkedListNode *)malloc(sizeof(SinglyLinkedListNode));
    
    if(head == NULL){
        head = newNode;
        newNode->data = data;
        newNode->next = NULL;
        return head;
    }
    
    SinglyLinkedListNode *temp = head;
    while(temp->next != NULL) {
        temp = temp->next;
    }
    newNode ->data = data;
    temp->next = newNode;
    temp = newNode;
    newNode->next = NULL;
    
    return head;

}
