Linked lists and classes

[nizbit]

First I just wanted to say thanks for all the help everyone has provided for me before. I'm sure you wanted to reach through the internet and strangle me :) .

I having some difficulty with understanding/implementing a linked list class with another class. Just something as simple as interacting with each class has me puzzled. Say I have a class called race car. This class contains the make, number, team and driver of the race car. Then say there is a race track class. This class will define a linked list for the race car class. The member functions might do a bunch of things like add, swap, delete and print. I'm not concerned with the member functions. Would something like this work:

class racecar {

      private:
          string make, team, driver;
          int number;
.
.
.
.
};

class raceTrack {
typedef racecar* ListItemType;

      private:
          racecar make, team, number;
          struct ListNode
	   {
	      ListItemType item;
	      ListNode    *next;
	   }; 
.
.
.
};

This is just an example I thought of. Could someone help me by using this example or show a different example? Thanks.

You don't need to write your own list!
Lists in c++

And "class" is reserved c++ keyword, you can't use it as varable named class!

[nizbit]

Sorry, I fixed the typo. I am working on an assignment and templates can't be used. Also I would like to add that the example is not my assignment.

In that case, I think it's fine. Just try to explain to me please what is line:
racecar make, team, class, number;
Why are you making instances of racecar class?

[nizbit]

Well class should not be in there. I thought I would have to make an instance so I could add a race car to the linked list.

[Sci@phy]

No, not about class keyword now :)
But what is make, team and number?
You use them as instances of class racecar, and I fail to see why do you need that.

But yet again, maybe it's my fault.

Try to write it, and see will it work :)

Yeah.. You can do that... You just declare the List and the class (for eg. Class car) as usual. The only thing special is that the ListItemType is car.

class Car
{
	private:
		string name;
		string team;
		stringdriver;
		int plate_number;

	public:
		..........
};

class List
{
	private:
		struct ListN
		{
			Car item;
			ListN* next;
		};

		ListN* head;
		ListN* tail;
		int size;

	public:
		...........
}

Great. Thanks for the help.
