   That actually declares m as an 20-element array of pointers to   
   R-member char. The correct declaration would be "char (R::*m)[20]", a   
   pointer to R-member 20-element array of char.

   As Daniel Krügler suggested, you can use templates. Let me add that   
   comparing built-in arrays by a simple == doesn't work and that you'll   
   probably want to use std::strcmp.   
      
   On the other hand, if you had used std::string in the first place, you   
   wouldn't have had to worry about this problem at all.
