types of objects

(Declaration: The following object-oriented ideas are based on C ++ and 2D graphics) In a program with a small amount of code, we may directly encapsulate the collision detection of all required objects in the class, and then Automatic Collision

It seems that you have noticed that, no matter how defined, it is likeC ++ linked listInObjectAre of the same type. In fact, this is also necessary. Otherwise, what is the type of the return value of a function such as the data in the returned node?

In peacetime use S:iterator this iterative label, generally we are the same type of multiple objects into a set, then, can we put different objects to iterate? Daily work may sometimes be necessary to simplify the program, I tested it today, as if
