Apparently your compiler is old and non-compliant.

I have vc++ 6.0, I haven't bothered looking into the most up to date
version, what would that be?

Current release is .NET (or "2003"), which is 7.1 (compiler v 13.1) and
2005, or v8 (compiler v14), is in Beta, last time I looked. The 7.1 is
miles ahead of 6.0, although not free from its quirks.

As Victor said, 7.1 (VS.NET 2003) is much better. It's about 98/99%
standards compliant. Also, in addition to the sort of construct you had
there, VC6 is notoriously bad with template code.

I'd highly recommend either 7.1 or a MinGW g++ variant for Windows
programming.

Not that this answers your question, but you'd better declare a copy
assignment operator to make the third in the "rule of three".
bool operator==(const Array &) const;
bool operator!=(const Array &) const;

virtual Type &operator[](int index) {return ia[index];}
virtual void sort();

virtual Type min() const;
virtual Type max() const;
virtual int find(const Type &value) const;

Type *ia;
};
