(hard) Flag loop variables declared ahead of the loop and employed once the loop for an unrelated intent.

An invariant is reasonable situation for that members of the object that a constructor ought to create for the public member functions to believe.

This point out of affairs has led more mature coding standards to impose a blanket need that all base course destructors has to be Digital. This is often overkill (even when it's the common circumstance); in its place, Source the rule ought to be to produce base class destructors Digital if and only When they are public.

Unfortunately, a specification can be incomplete or inconsistent, or can fail to satisfy buyers’ affordable expectations.
