What is a static constructor?

Question

This question was asked to me in an interview:

What is a static constructor?

Does it exist in C++? If yes, please explain it wit

Answer 1

Other way to emulate static constructor behaviour is to use instance variable with private constructor and static factory method.

Cat* Cat::give_birth() {
  static Cat *myone = NULL;
  if (myone == NULL) {
    myone = new Cat();
  }
  return myone;
}
