Resizing Arrays in a Class

This is what I am using right now (doesn't work). The AddLeaf function only works the first time thru, when there are 0 nodes.

PHP Code:

---

class NodeTree
{
public:
    NodeTree();        // Constructor
    ~NodeTree();    // Deconstructor
    bool AddNode(Node *Left, Node *Right, long Tag);
    bool AddLeaf(char Character, long Tag);
protected:
    long NodeCount;
    Node *TheNodes;
};

...

bool NodeTree::AddLeaf(char Character, long Tag)
{
    int i = 0;
    Node *TempNodes = new Node[NodeCount];
    for(i = 0; i < NodeCount; i++)
    {
        TempNodes[i] = TheNodes[i]; //Error!
    }
    delete[] TheNodes;    
    Node *TheNodes = new Node[NodeCount + 1];
    for(i = 0; i < NodeCount; i++)
    {
        TheNodes[i] = TempNodes[i];
    }
    delete[] TempNodes;
    TempNodes = NULL;    
    TheNodes[NodeCount].Character = Character;
    TheNodes[NodeCount].Type = Leaf;
    TheNodes[NodeCount].Left = NULL;
    TheNodes[NodeCount].Right = NULL;
    TheNodes[NodeCount].Tag = Tag;
    NodeCount++;
    return true;
}

I saw something that was redundant in your code.

-----
// Node *TheNodes = new Node[NodeCount + 1];

// TheNodes is declared in class declaration
// this will work fine

TheNodes = new Node[NodeCount + 1];

What is NodeCount initialized to?

Kuphryn

try changing you assigning for statement to this:

Code:

---

*TheNodes[i] = *TempNodes[i];

---

It looks like right now you were assigning memory addresses and not values.

Thanx, kuphryn that worked perfectly! Initially, NodeCount is 0, btw.
