  1. You should do insert at tail, also add the base case inside insertTail() that if head==NULL, create new node for head and return.
  2. wrong class node, inside constructor you are doing d = data, it is opposite bro.
  3. Also inside the appendk function, you need to update the correct head before returning, i.e. head = curr.

I have done the changes in the code for better understanding but i will suggest you first try to do by yourself
