WebAug 3, 2024 · Static data member in-class initialization Things are more complicated here because there has to be just 1 symbol for the static data member. You should read about ODR (One Definition Rule). Let's start with const static data member. You might be surprised that initialization is allowed only from compile time constant expressions: The process of verifying and enforcing the constraints of types—type checking—may occur at compile time (a static check) or at run-time. If a language specification requires its typing rules strongly (i.e., more or less allowing only those automatic type conversions that do not lose information), one can refer to the process as strongly typed, if not, as weakly typed. The terms are not usually used in a strict sense.
