My second C++ lab, bit of fun if i do say so my self.

Its a stack that uses a linked list in C++ alot of debugging stuff still in here, but I like the debugging output anyway.

Sorry about the lack of comments and

#include <iostream.h>

typedef struct TAG_NODE {
        int data;
        TAG_NODE* NOS;  //Next on stack
} node;

class Stack{
private:
        node* TOS;
public:
        Stack();

        int pop();

        void push(int myData);
};

        int data;
        if (TOS != NULL){
                // Node to temporaly store the TOS
