Remove all nodes in linked list

Question

I have a linked list contains 3 nodes like the image shown:

There is a head pointe

Answer 1

To delete all nodes except the first node, you can try below code.

temp1 = head->next;
while(temp1!=NULL) // as I am considering tail->next = NULL
{   
    head->next = temp1->next;
    temp1->next = NULL;
    free(temp1);
    temp1 = head->next;
}

This will delete all nodes except first one. But the data with the first node will remain as it is.
