Destructor for static fields. Singleton realization

Question

So, classic simple Singleton realization is following:

class Singleton
{
private:
    static Singleton* singleton;
    Singleton() {}
public:
    static Sing         


        

Answer 1

When a variable local to a function is declared "static", it means that it isn't allocated on the stack - and that its value persists from one call to the next.
