static variable in the class declaration or definition?

Question

I am new to C++.
I have a class like this:

class CodeTest
{
private:
    static const int TOTAL=100;
};

Is TOTAL a dec

Answer 1

static const int TOTAL=100; // is a declaration followed by an initialisation.

From the C++ standard section 3.1:

A declaration introduces names into a translation unit or redeclares names introduced by previous declarations. A declaration specifies the interpretation and attributes of these names.

The next paragraph states that a declaration is a definition unless...... it declares a static member within a class definition:

struct X
{
    int a;         // defines a
    static int b;  // declares b
};
