How to display data in a bst in tree format using C++?

[techie929]

I have to display nodes in bst in the below given format:

I have insesrted the nodes properly and able to display it using preorder.

if the nodes are F,D,E...the output should come as:

F
 + - - D
          + - - NULL
          \ - - E
                  + - - NULL
                   \ - - NULL
 \ - - NULL

Probably your display function needs to be recursive. As it walks the tree itIt should call itself when the next pointer is not NULL.
