Here you go:

#include 
#include 
using namespace std;

template 
T my_max(T a, T b)
{
   if(a > b)      
      return a;
   else
      return b;
}

template 
class D
{
public:
   D(classT in)
      : d(in) {};
   bool operator>(const D& rhs) const { return d > rhs.d;};
   classT operator=(const D& rhs);

   template friend ostream& operator<< (ostream & os, const D& rhs);
private:
   classT d;
};

template ostream& operator<<(ostream& os, class D const& rhs)
{
    os << rhs.d;
    return os;
}


int main()
{

   int i1 = 1;
   int i2 = 2;
   D d1(i1);
   D d2(i2);

   cout << my_max(d1,d2) << endl;
   return 0;
}
