Static variables in static method in base class and inheritance

Question

I have these C++ classes:

class Base
{
protected:
    static int method()
    {
        static int x = 0;
        return x++;
    }
};

class A : public Base         


        

Answer 1

There will only be one, shared by all three classes. If you want separate instances, you will have to create separate functions in the derived classes.
