Modular Programming: A Classless Approach Part I

Why is main() returning void in the example used in this article? Also what''s wrong w/ using classes in C++ to accomplish what the author''s trying to do in the article? Wouldn''t there also be a problem in using a linked list for keeping track of the instances of the objects? If you need an object that''s in the middle of the list you''ll have to traverse through the list to get to that object. That doesn''t seem very efficient to me.

Since the non-class approach is already using an struct, why not just use an struct for the instances instead of all those problems. SDL works like that without using classes.
