Singletons

[liquifiednate]

I'm messing just now learning about singletons and was wondering if it is at all possible to change your singleton at all? For example I created a date Singleton and I know I can only have one constructor controlling it but is it possible to change it later on? Here's what my main file looks like.

int main()
{
  Date *date1 = Date::instance(3, 2014, "March");

  date1->print();
  date1 = Date::instance(5, 2014, "May");
  date1->print();

  return 0;
}

which works just fine but I've tried everything I can to be able to change the values later on and can't figure out how to do it. I understand Singletons are made so you don't have multiple constructors but is it possible to change its values at all later on?

You change the values like any other class. Show us how you tried to do it that didn't work.
