Meyers singleton--Why cant we create two objects?

[venkatacplpl]

Singleton& Singleton::getInstance() {
static Singleton instance;
return instance;
}

When We define getInstance() method like above...then

int main()
{
    singleton*s1=singleton::getInstance();
    singleton*s2=singleton::getInstance();
return 0;
}

when we execute above code .doesnt getInstance() method execute
static singleton instance line twice and create two different instances?

getInstance() is called twice, but both calls return the address of the same object.

Why cant we create two objects?

Singleton is a "pattern" that describes that effect. The code is just an implementation of that pattern.
