    Binary Search Tree Insertion Algorithm Help

    I have looked high and low on the web for the insertion algorithm for a BST. Can anyone either point me in the right direction or provide one for me. Thanks!!

    1) compare new node vs. root node

    2) LOOP: if less, return node->left. if greater, return node->right.
    Test for a terminating case w/ each iteration.

    3) Now you have a pointer to where the node is supposed to be inserted.
    Make the proper pointer assignments to make the insertion.

    how do i initalize the first node, use a constructer in my node declaration to set the pointers *left and *right to NULL, then in my gooey of the "insertNode" alg, do i set "node Newnode = new node"?
