Edit Question
Title
Body
imagine I have a bunch of C++ related classes (all extending the same base class and providing the same constructor) that I declared in a common header file (which I include), and their implementations in some other files (which I compile and link statically as part of the build of my program). I would like to be able to instantiate one of them passing the name, which is a parameter that has to be passed to my program (either as command line or as a compilation macro). The only possible solution I see is to use a macro: #ifndef CLASS_NAME #define CLASS_NAME MyDefaultClassToUse #endif BaseClass* o = new CLASS_NAME(param1, param2, ..); Is it the only valuable approach?
