Ok guys, after getting the foolish error in my code, now I release the (almost, half some functions to add) whole code of the Binary Search Tree in ANSI C.

CHANGELOG:

-Update 1: Added the PreOrder and PostOrder traversal methods/functions.
-Uptade 2: Added the Search method/function.

Binary Search Tree --- damn it!!

PROBLEM FIXED!!

The problem was at line 68 @ bst.c, self_node was a pointer to a pointer structure, so to make a bifurcation it's necessary to use the * operator, but I had self_node without the * operator. But now the problem is fixed, and I can continue programming more functionts to the tree.

Hi people,

In the "Data Structure" class, I had to build a Binary Search Tree with some functions related, so I tried to make the program in ANSI C with some OOP emulation (something of "Object-Oriented with ANSI C" by Axel-Tobias Schreiner), but I got a little trouble, the _insertItem() function doesn't work (line 67~74 @ bst.c file). Really, I have no idea what is going on in those lines, they are supposed to work, but they aren't.

So people I need your help, because I don't know how fix it. :(

Thanks!


PS: If you found that my english sucks tell me! I need to improve it. :D
