log n + 1 is NOT the height of a binary tree, it is only the minimum height.  The height is only lob n + 1 when the tree is balanced.

I use to see that mistake all the time when I taught this stuff, so I feel obligated to pick on it.


Anyways, there are two approaches you can take.  If you've tracked the number of nodes in the tree, then you can just run the formula you stated.  The other method is to use the first segment of a depth-first traversal.

this is a recursive c (or c++) function:

int height(node * p_root) {
  if (p_root) {
    //fing the height of the left and right sons
    int left_height = height(p_root->left);
    int right_height = height(p_root->right);

    //return the max height (max(left,right))
    if (left_height>right_height) return  left_height+1;
    else reutrn right_height+1;
   
  } else  return 0; //if this is the bottom  of the tree

}
