 One of the advantages of implementing classes with inheritance is **code reuse**.  Almost all class-based object oriented languages let you define derived classes //without having to re-write the base class code//. The idea is that you write the base class code //once//. Then when you write the derived classes, you add only whatever new code is required for the derived class or new definitions for old code that must be **overridden**.
-Since you do not need to rewrite the code that is common to both base and derived classes, you end up writing less code. But even more important, when you fix a bug in the base class, it automatically propagates down to the derived classes.
