let's say I have a class animal and a class dog that inherits animal. Let's say I want to call a method called 'eat()' that is specific to dog but there is some shared eat code between all animals, so I know I can make 'eat()' virtual but then it won't use the base class code, should I just call my base class 'eatAll()', for example, and then every eat method from a specific animal will have to call that? Just looking for the best design I guess. This is in c++
