For a hard and fast-size array, use std::array, which isn't read what he said going to degenerate into a pointer when passed to a functionality and does know its dimensions.
This will produce too many Bogus positives in some code bases; If that's so, flag only switches that manage most although not all scenarios
Then, Regardless that the destructor should be community, there might be good force to not ensure it is virtual mainly because as the main Digital perform it could incur many of the run-time kind overhead in the event the additional functionality should really by no means page be needed.
