case for uninitialized variables in C++ being an advantage in
that you can potentially get a warning regarding use of an
uninitialized variable that points out an error in your code.

This is grat when it works, but the problem is that it would be
gargantuan effort -and compile time sink- to make it work
perfectly. When it's just about if-else if chains, switches or
boolean logic as in the example, the analysis won't be too
complicated. But swap those booleans out for a string, and make
the conditions to test whether it's a phone number, and whether
it satisfies some predicate implemented in a foreign langauge,
and you'll see where the problem is.
