Problem on template specialization

Dear All,

I have a simple code, but it has some problem in cimpiling. Would you
please help me to look at it?

template<class Type, size_t N>
class Vector
{
private:
Type data[N];

public:

template<size_t i>
Type Product() const
{
return data[i] * Product(i+1);
}

template<>
Type Product<N>() const
{
return 1;
}
}

The compilor error is that:

Error 1 error C2975: 'i' : invalid template argument for
'Vector<Type,N>::Product', expected compile-time constant expression

What I assume is that N is a compile-time constant expression. I
appreciate your help.

Bests,

Shuisheng

There is no Product() function that takes an integer as argument in your

Which line does that error refer to?
Well, you haven't showed how you are instantiating your template.

Vector<int, 4v(1);
int prod = v.Product<0>();

Thanks.

You can't specialize a class function on the class template parameter.
You can't use 'N' as the specialization. I can dig up the standard-eze
if you'd like.
