singleton, there are a lot of use in design pattern

static Singleton s;
int i;
Singleton(int x) : i(x) { }
void operator=(Singleton&);
Singleton(const Singleton&);
public:
static Singleton& getHandle() {
return s;
}
int getValue() { return i; }
void setValue(int x) { i = x; }
};
Singleton Singleton::s(47);
int main() {
Singleton& s = Singleton::getHandle();
cout << s.getValue() << endl;
