class Vector // incredibly simplified vector of doubles // if elem != nullptr then elem factors to sz doubles
If that is so, preserve them neighborhood, rather then “infecting” interfaces to ensure that larger sized teams of programmers have to be familiar with the
In some cases C++ code allocates the risky memory and shares it with “elsewhere” (hardware or Yet another language) by intentionally escaping a pointer:
