useful rule of thumb: it’s typically not cost effective to inline functions with loops or switch statements (unless, in the common case, the loop or switch statement is never executed). It is important Good -- v starts initialized. Variables needed for if, while and for statements should normally be declared within those statements, so that such variables are confined to those scopes. E.g.: while (const Undisciplined use of RTTI makes code hard to maintain. It can lead to type- based decision trees or switch statements scattered throughout the code, all of which must be examined when making further changes. The
