Hi all
I am looking for an exercise for myslef that will take 3-4 hours to practice pholymorphism/abstraction do you have idea for exercise, or do you know where can I get one?
searching the net I found easy question, and I want something that will take 3-5 hours
thanks
implement a data driven finite state machine framework (build state and transitions described by data given in files).
Option 1: support various file formats: xml, binary(+editor)
Option 2: Support states that are state machines them self
Option 3: graphical output of state machines
Option 4: graphical input of state machines (should not be possible in your time frame)
Option 5: Build an execution environment, so the machines can do something meaningful
That should include a lot of abstraction and polymorphism as well
Common first polymorphism class would be an "animals" class, where you start with a basic anmial, and then derive classes like cat, dog, fish, parrot, etc.
That may be too simple, but it's a starting point for learning polymorphism.

You could make a kd-tree, and use polymorphisms for the nodes. Wiki it, it's can be used for many different things, but I use it for collision detection in my games.

That's exactly what I was thinking about. That or a Shape class like in Bjarne Stroustrup's book.Quote:

You can make a program that will find the answer to life the universe and everything.
