I was perusing my codebase and I noticed a number of places where virtual methods from a parent class were being masked by virtual methods from the child class (e.g. ParentClass has a virtual method foo(int i=8). ChildClass is a ParentClass and has a virtual method foo(void)).
If you have:
Child myChild;
Parent *pParent = &myChild;
myChild.foo();
pParent->foo();
pParent->foo() is not calling the same routine as myChild.foo().
This can be detected by using the -Woverloaded-virtual flag when compiling files. Note that this doesn't warn if a nonvirtual method in child masks the parent method (presumably the nonvirtual method in ChildClass would indicate that things are supposed to work the way they do).
So not a techie: Upon first glancing at this entry, I of course skipped to the programming part, and I thought you were trying to illustrate some parent/child dynamic, or some family relationship thing. Heh. Silly me.
Also, why are you posting at 4 AM? Is that 4 AM your time or mine? (Not that I haven't been online at 4 AM in previous years...)
