Even redefining "=" operator (or defining as the default just one is instantly discarded for The explanations you explained),I can't assign a worth to some static value.

Last, and not minimum, this kind continue reading this of followup helps All people who assisted really feel a satisfying sense of closure about the situation. Issue narratives that trail off into unresolved nothingness are annoying matters; programmers itch to check out them settled.
It's going to take fantastic coding type, library guidance, and static Investigation to eliminate violations without the need of significant overhead.
Make discover here your best small foundation library and use that, as opposed to lowering your level of programming to glorified assembly code.
Do the most effective you'll be able to to anticipate the queries a respondent will check with, and respond to them upfront in the request for help.
A rule can do hurt by failing to ban something which allows a significant mistake inside of a given situation.
