Thank you for every one that replied on my post, and gave me advice.
At the end this is how I did it.

typedef void (Convert::*FUNCPTR )( void ) ;
typedef std::map< std::string,FUNCPTR > MapItem;
MapItem functionTable;
functionTable["$* GRID CARDS"] = &Convert::writeVerts;
functionTable["$* ELEMENT CARDS"] = &Convert::writeCell;
functionTable["$* LOAD AND CONSTRAINT CARDS"] = &Convert::writeBoun;
