Top Forums Programming Dynamically enumerating the members of a C++ struct Post 302810961 by Corona688 on Wednesday 22nd of May 2013 07:41:34 PM

You can't do that sadly. What I usually see done when this is needed is one of two things:

* Some sort of dynamic structure, like a map or hash or list, without predefined contents.

OR

* Use a script to build the structure out of some sort of data file, and also build an array which describes its contents.
