Can the C + + static variable itself be an instance object

The general book always uses int to give an example, that is too simple. What if the static variable itself can be an instance object? It should be possible, but this involves its constructor and how its internal static variables initialize two questions, in other words, how should the static variable itself be initialized? This problem is related to the singleton pattern, and we look back.

The following is an immature example, but can be compiled and run through.

#include"stdafx.h"#include<iostream>using namespacestd;classaaa{ Public:    Static intSSS; intddd;};intAaa::sss = -;classMyClass { Public:      Staticaaa*A; StaticAAA BBB;  MyClass () {}}; AAA* Myclass::a =NewAAA ();//Int (myclass::a)->sss =;intMain () {cout<< myclass::a->SSS;       GetChar (); return 0; }
