C++ stacked link list using node class

I am trying to figure out how to write a program in C++ that will use the stack data type. I cannot figure out how to write the functions that will push and pop the stack, as well as display the stack.

The program I write needs to include the following code into it. Can someone help me?

#include <iostream>
#include <stack>
using namespace std;

class node {
    void *info;
    node *next;
public:
    node (void *v) {info = v; next = 0; }
    void put_next (node *n) {next = n;}
    node *get_next ( ) {return next;}
    void *get_info ( ) {return info;}
};

class list {
    node *head;
    int node_num;
public:
    list ( ) { node_num = 0; head = 0;}
    void remove (int);
    void insert (void *, int);
    void append (void * v) {insert (v, node_num + 1); }
    void *find (int);
    void display ( );
};
