Compiler Error C2253

'function' : pure specifier or abstract override specifier only allowed on virtual function

A nonvirtual function is specified as pure virtual.

The following sample generates C2253:

// C2253.cpp
// compile with: /c
class A {
public:
   void func1() = 0;   // C2253 not virtual
   virtual void func2() = 0;   // OK
};

The following sample generates C2253:

// C2253_2.cpp
// compile with: /clr /c
ref struct A {
   property int Prop_3 {
      int get() abstract;   // C2253
      // try the following line instead
      // virtual int get() abstract;

      void set(int i) abstract;   // C2253
      // try the following line instead
      // virtual void set(int i) abstract;
   }
};
