deleting binary trees??

Question

what happens if you delete
the root of binary tree without deleting the nodes?

Answer 1

Well theoretically the nodes still exist, but no way to reference them unless you had saved a link to them directly w/o having gone through the root

Answer 2

shadowkat is right, u dont know where they are unless u have saved their address. So u have essentially deleted only the root of ur binary tree. althought they still exist in the RAM, infact in the data-segment, they will be erased once your program quits.... data segment will be flushed...... but its always a good habit to manually free any memory that u used in the program....
