Trees implimentation...!!!PLZ HELP!

[momotaro]

this is the structer:

typedef struct tree Tree;
struct tree{
int value;
Tree *left,
       *right;
};

plz which of the following implimentations is more accurate:

int TreeSize(Tree *root){
int count = 0;
if(root == NULL) return 0;
else{
      TreeSize(root -> left); count++;
      TreeSize(root ->right); count++;
      return count;
      }
}

*********************************OR*************** *************

int TreeSize(Tree *root){
int h1,h2;
if (root == NULL) return 0;
else{
       h1 = TreeSize(root -> left);
       h2 = TreeSize(root -> right);
       return (h1+h2+1);
       }
}

P.S:if there is any other suggestions go ahead!
THK!

The second one is better, because it is the only one that works.

The first function always returns 2.
