a decleration must be available error

[curious2007]

I am trying to get rid of errors in a vector template. This is one of the errors.
In vector.hpp the vector template has been declared as follows:

template <class V, class I=int, class S=FullArray<V> > class Vector: public Array<V, I, S>

And in array.cpp I have implemented size() and MinIndex() functions. So when I try to use these in vector.cpp, I should not have any problems but the following code in vector.cpp gives me error.

template <class V, class I, class S>
Vector<V, I, S> Vector<V, I, S>::operator / (const V& a) const
{ // divide every element by a

// Create new vector of same size and same starting index
Vector<V, I, S> result(Size(), MinIndex());

// Copy all elements /a
for (I i = MinIndex(); i <= MaxIndex(); i++)
result[i] = (*this)[i] / a;

// Return result
return result;
}

I get the following errors:

there are no arguments to `Size' that depend on a template parameter, so a declaration of `Size' must be available

there are no arguments to `MinIndex' that depend on a template parameter, so a declaration of `MinIndex' must be available

there are no arguments to `MaxIndex' that depend on a template parameter, so a declaration of `MaxIndex' must be available

I would appreciate any insights.

Where, in relation to that code, have you declared those functions? It looks like, from those errors, that the template class you declared is looking for those definitions as well, but I couldn't see them in there.

I have declared them in array.hpp and implemented them in array.cpp.
