The widespread scenario for a foundation course is it’s meant to have publicly derived classes, and so contacting code is pretty much sure to use a little something similar to a shared_ptr:
If We have now 1,000,000 lines of latest code, the thought of “just altering it suddenly” is often unrealistic.
To write down a base class is to define an abstraction (see Products 35 by means of 37). Recall that for each member operate participating in that abstraction, you must make a decision:
Accidentally leaving out a split is a reasonably frequent bug. A deliberate fallthrough is usually a servicing hazard.
