hey everyone, im doing this Binary Search Tree, and well i got the insert, retrieve, and traversal functions to work, but my teacher also wants us to do a Node Summary. My teacher wants us to find out how many internal nodes there are in the tree, and i dont know how to do that, i made this while loop to go through the tree, but the program for some reason wont even execute it.

below is the site to my program, its only one function, so its not long


Thanx, and to email me, email me at DRFUNKENSTINE@aol.com
