because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
Does the static qualifier prevent from the memory allocation for the endless series of int i? I am not quite sure because any new Egg object (thus, int i) is in an inner scope (e.e...), even static says that all Egg objects share the same static memory for that member. ???
I understand that making the constructor private prevents the class user from creating any object, leaving us only with the shared static data member, previously defined by the class creator. Right?
Thanks for reading
