I'm not going to write the code for you, but I'll try and explain it.

I think of delete from end and delete from middle as being the same basic operation.

Point a temporary pointer at the element you want to delete. Modify the pointer of the element before it to point to the next pointer on the element you want to delete.


So if we want to delete d we set temp = d and set c = d->next (which is null in this case, but could easily be an element). Then you can simply delete d.

That make sense?
