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

The variable will be shared - it is per-function - in this case the function it belongs to is Base::method(). However if class Base was a template class you would get one instance of the variable for each instantiation (each unique set of actual template parameters) of class Base template - each instantiation is a new function.
