Alright. But then someone should probably have reminded you that a long
time ago.
Maybe you missed it when an Ada integer overflow bug produced one of the
most expensive software bugs in history by crashing the Ariane 501
rocket and its 4 cluster sattelites payload.
As I recall, the software did exactly what it was supposed to do in
that situation...
But no one had tested the algorithm with the rate of change the Ariane
5 could produce -- so an algorithm that was developed for, and safe with,
the smaller Ariane suddenly went "something's wrong -- abandon ship"
Nothing inherent in the language...
What would C++ have done in the same situation? Would Ariane still have
failed? Probably...
