Specifically, we’d really like to acquire many of our rules backed up with measurements or superior illustrations.
// low-priced: one increment addresses this entire purpose and all the call trees beneath us auto pin = g_p; // Very good: passing pointer or reference received from a neighborhood unaliased smart pointer file(*pin); // GOOD: very same cause pin->func();
If enter isn’t validated, each and every perform must be prepared to cope with undesirable facts (and that is not practical).
