strange return value

I'm writing a binary tree and having some problems. In my delete method, I return 1 if the root is the only node in the tree and it is deleted and a 0 in every other case. When I run the program, for some reason in a certain case, I get the value of 163920. Here's the code for that case:

Code:

---

if(right == NULL && left == NULL)
{
  BTN *t = this;
  if(parent == NULL)
  {
    delete t;
    return 1;
  }
  /*int lorr = parent->lorr(name);
  if(lorr == 1)
  {
    parent->left = NULL;
    //parent = NULL;
    delete t;
  }
  else
  {
    parent->right = NULL;
    //parent = NULL;
    delete t;
  }*/
  delete t;
  return 0;
}

---

The node I'm trying to delete ought to return 0. Does having that "delete t;" mess with the return? Any help is greatly appreciated.

I've heard about compiler problems with returning a value that isn't in parenthesis, so you may wish to use them, as so:

return(1);
return(0);

just to ensure that it is compiling properly.
