Not an "error" but an important omission, and it may just be a Microsoft variation,
but here goes:

In Microsoft Visual C, a static variable declared in a class must also be declared at
file scope, outside the class declaration. Also, if it is going to be initialized to
some value, it can only be initialized at file scope.

So the declaration would be:

class Foo {
public:
...
static int staticDataMem;
...
};

int Foo::staticDataMem; // File scope declaration
/* or
int Foo::staticDataMem = 3;
*/

I spent a little time pulling my hair out until I found this in Microsoft
documentation.

Note from the Author or Editor:
I don't have access to a Microsoft compiler to test this.
