Member functions of a class can be defined either outside the class definition or inside the class definition. In both the cases, the function body remains the same, however, the function header is different. Outside the Class: Defining a member function outside a class requires the function...
These rules apply to inline functions whose definitions appear within a class definition. In addition, static local data and strings in inline functions maintain the same identities between the DLL and client as they would in a single program (that is, an executable file without a DLL interface...
