csf.SeekToBegin();

for(int i=1; i<=iSize; ++i)

    csf.WriteString(sTemp);
}
csf.Close();

I think it means an operator &, which returns const Inner* type and takes no arguments, right?

const Inner* pInner = &objOuter\\ object of Outer or the class within which the operator is defined
error C2440

const Outer::Inner * operator &();

Outer OuterObj;
const   Outer::Inner *   innerObj = (const   Outer::Inner * )(OuterObj);
or
const   Outer::Inner *   &innerObj = (const   Outer::Inner * &)(OuterObj);

This compiles, but the member operator function is not invoked.

So now you can compile without error
