Thanks Steven,

      Didn't mean to snip that out.. I overlooked it as just a warning. So
here is the updated code.

 #include <boost/static_assert.hpp>
template<class T = int, std::size_t N = 3>
class C {
public:
   C() {assign(0)}
   C(const T& i0) {
       BOOST_STATIC_ASSERT(N == 1);
       m_data[0] = i0;
   }
   C(const T& i0, const T& i1) {
      BOOST_STATIC_ASSERT(N==2);
      m_data[0] = i0;
      m_data[1] = i1;
   }
   const_iterator begin() const {return m_data;}
   const_iterator end() const {return m_data + N;}
   void assign(const T& value) {std::fill_n(begin(), size(), value);}
   static size_t size() {return N;}
   ...
   ...
private:
   T m_data[N];
};
typedef C<> my_C;

   Apologies... but I am unable to see what the MS VC++ 2010 compiler
doesn't like about this..

Thanks for pointing this out,
--Sunil.
