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

First part of the question:

This line: static const int TOTAL=100; is a declaration followed by an initialisation.

TOTAL is an identifier.

Second part of the question

const int CodeTest::TOTAL is required to initialize the variable.
