Flag a vector whose dimensions under no circumstances alterations right after building (including because it’s const or because no non-const functions are identified as on it). To fix: Use an array alternatively.
If that is so, hold them nearby, as an alternative to “infecting” interfaces so that larger sized teams of programmers really have to know about the
