Help to translate from ADA 2 C/C++

[rgelb@csulb.edu (Robert Gelb)]

I am having a hell of a time trying to translate this ADA program into 
C/C++.  Maybe someone can help me.
Here is the program:

type person(sex:gender);
type car;
type person_name is access person;
type car_name is access car;

type car is 
	record
		number: integer;
		owner: person_name;
	end record;

type person(sex:gender) is 
	record
		name	:string(1..20);
		birth	:date;
		age	:integer range 0..130;
		vehicle	: car_name;
		case sex is
			when M =>
				wife: person_name(F);
			when F =>
				husband:person_name(M);
		end case;
	end record;
