FAQ Printing a binary tree?? (C)

[QuestionC]

Still not too sure what your asking, but here goes...

1) The generic treeprinting program

void printtree(node * tree)
{
 if (tree != NULL)
 {
  print (tree -> info); // Not a real command
  printtree (tree -> left);
  printtree (tree -> right);
 }
}

2) If you want a graphical tree, might I suggest something using ASCII characters 179, 192, and 195? You know, just do those to draw lines from nodes to their children, with each node being on a different line. It's not spaced out as a tree diagram usually is, but it does have connectivity lines, which is the importatnt thing, personally.
