A virtual function error

i am working in ubuntu
so please help so that it works in ubuntu

/*Write a program having a base class- num. Have this class hold  an integer value  and contain a virtual function shownum(). Create two  derived classes- displayhex and displayoct that inherit class num. Have  the derived classes override  shownum() so that to display  the value in heaxdecimal  and octal respectively.*/


#include
 
using namespace std;

class num
{
 protected:
  int i;
 public:
  num(int n)
 {i=n;}

 virtual void shownum()
  {
    cout<>i;
  hex h1(i);
  num *h;
  h=&h1;
  h->shownum();

 return 0;
 
  delete h;

    I got a Red Hat Enterprise Linux. i didn't actually understand what you expect by making it work in ubuntu. Is it working in all other platforms? will making it compile in linux do?

    #include 
using std::cout;
using std::endl;
using std::ios;

class num
{
protected:
    int i;
public:
    num(int n)
    {
        i=n;
    }

    virtual void shownum()
    {
        cout<<"the value of i is "<shownum();
    objOct->shownum();

    delete objOct;
    delete objHex;
