Copying a linked Stack in C++?

I have a linked stack that I would like to copy over in to another stack so that it becomes in reverse order. How would I do that??








Basically this is how my stack is made.





struct Node


{


int num;


Node *Link;


};





MyStack::MyStack()


{


stackTop = new Node;


stackTop = NULL;


}


void MyStack::push(int num)


{


Node *newNode;


newNode = new Node;





assert(newNode != NULL);





newNode-%26gt;num = num;


newNode-%26gt;Link = stackTop;


stackTop = newNode;


}





Theres more to the code but this is all that matters for my question.





Thanks!

MyStack::MyStack()


{


// stackTop = new Node; // this "new Node" would be a memory leak


stackTop = NULL;


}








MyStack::( MyStack %26amp; o ) {


stackTop = NULL; // init my head


Node **ppNode = %26amp;stackTop; // point to pointer


Node * pNode = o.stackTop; // get other stack's head


while (pNode != NULL)


*ppNode = new Node; // make a new node


**ppNode = *pNode; // copy the other stack's node


(*ppNode)-%26gt;Link = NULL; // clear the new node's link


ppNode = %26amp;(*ppNode)-%26gt;Link; // point to the new node's link


pNode = pNode-%26gt;Link; // move to the other stack's next node


}


}
