Hello Everyone.

Project outline:

So far this is what I've come up with:
I made the following classes;

Car Class -- stores car model, car price
Dealer Class -- stores dealer name, dealer id
Transaction Class -- inherits from Car and Dealer
Distributor Class -- has the operation to add, remove transactions etc..
Node Class -- linked lists

I don't think I'm doing this right, Any suggestions on how to design this, on how many classes I should use would be appreciated.

Thank You.

Just a quick question before I can help you: how long have you been programming using C++?

1 Year now...

Great! then you should know about member functions. what I would suggest is instead of having a class that just does the add/subtract transactions is have those in the transaction class. also, can you use your own header files? does/can this be modular or does it have to remain in the same file?

So If i wanted to do a Stock of car models for the Distributor I should make a Car Node ?


I need to make a stock which has a number of car types (Toyota, Mistubishi, etc..)
I should assign an initial value of how many cars I have ( Toyota 200, Mistubishi 100...)
Then when I sell for example 50 Toyotas and 20 Mistubishis It should be subtracted from
my stock, I also should be able to add new cars or add more Toyotas to my stock which will raise the number of the Toyotas I should also be able to add new models and set their prices...

Cal I achieve that by making a CarNode ? I'm really haveing a hard time thinking this though if theres no much trouble could you give me a code example ?

That's a start, but you really should declare the model as a string. When you declare it as a char that, generally, only allows you to store a single character into the variable. With a string, you can include the entire name. Also, as a part of it you should include a variable that stores the number of cars available. Or if you wanted you could declare another struct that includes the number of cars available (but I think this would be a bit too complicated) Also, I believe you stated that you need to store the price of that model, so I would suggest another variable that stores that price.

So, here's what I suggest:

So, now that you have your carNode, you can create other classes or structs that'll change the amount of cars you have. I hope this helps.

Why u use struct instead of class since class is private by default and struct is public buy default ?

This is not a good OOP design principles.

True, but it really doesn't matter since you can make any part of a struct or class private or public. It depends on what the programmer is comfortable using. I just suggested a struct because that was what the original design.

By the way, TS3BxL, you never answered me: can you create your own header files and modules or does this have to be in a single file?

my bad, Yes you can create your own header files and modules...

do you need anymore help at the moment?
