| • | This
means your constructor would NOT set head to |
|||||||||||
| null |
||||||||||||
| – | in
fact, there should be no situation where head is null!! |
|||||||||||
| //constructor: |
||||||||||||
| head =
new node; |
||||||||||||
| head->next
= NULL; |
||||||||||||
| – | problems
occur with a destructor if it is ever explicitly |
|||||||||||
| invoked.
Why? |
