Answer 3

Recursion is used wide. For example you have a data structure like a tree. Each node of the tree is a class. You call a function at the root element. It performs some action and calls the same function for each child. It is completely the same function, but executed for other instance of class or it's inheritance. Most of User Interfaces are implemented in this way by inheriting all UI controls from the base UIItem an organizing them into a tree.
