In C++, you can't be nearly as carefree. Only mechanism (method code), but not representation (data bits) can be overridden in subclasses. Therefore you're usually better off not putting the data structure in a class. This leads to a stronger reliance on Abstract Base Classes (ABCs).
I like to think of the difference between an ATV and a Maseratti. An ATV (all terrain vehicle) is more fun, since you can "play around" by driving through fields, streams, sidewalks, and the like. A Maseratti, on the other hand, gets you there faster, but it forces you to stay on the road. My advice to C++ programmers is simple: stay on the road. Even if you're one of those people who like the "expressive freedom" to drive through the bushes, don't do it in C++; it's not a good fit.
