Accessors vs. public member variables

Steinar, you use accessor rather than public data members because you may need to change the behaviour of the class to do something when you set a member variable. If you have all your data public, you can't do this. If you force people to go via a function, you can make changes to the class without affecting its users. You have a similar issue with inherited classes.
