You will discover environments where by restrictions on use of ordinary C++ language or library attributes are needed, e.g., to stay away from dynamic memory allocation as demanded by aircraft Management computer software specifications.
Flag switch-statements more than an enumeration that don’t tackle all enumerators and do not need a default.
// low cost: 1 increment covers this entire functionality and all the call trees down below us car pin = g_p; // Superior: passing pointer or reference acquired from an area unaliased clever pointer file(*pin); // Very good: very same cause pin->func();
