Compiler Error C2503

'class' : base classes cannot contain zero-sized arrays

A base class or structure contains a zero-sized array. An array in a class must have at least one element.

The following sample generates C2503:

// C2503.cpp
// compile with: /c
class A {
   int array [];

class B : A {};    // C2503

class C {
   int array [10];

class D : C {};
