Help with HW

I am trying to compile this 7 file program but I've hit some road block. Here is the list of files I will be posting;

BankAccountMain.cpp
BankAccount.h
BankAccount.cpp
CheckingAccount.h
CheckingAccount.cpp
SavingsAccount.h
SavingsAccount.cpp

Ok and now for the coding...

Any and all help is much appreciated.

Which errors are you having trouble with? Most of them seem pretty self-explanatory.
ocdjg (28)
To be honest I'm not sure why I'm getting these errors in the first place. I thought the code looked solid, and individually they compile.
ocdjg (28)
OK the default constructor I get, I did miss that. The others I'm not so sure on. How do I get the functions to become members of the class? I thought I did that.

As an example, lets look at the error concerning setAccountNumber(). The error says that it is not a member of SavingsAccount, and upon inspection I see that is the case; the members of SavingsAccount are those listed on lines 11-13 and 17-22 of SavingsAccount.hpp. There is no mention of the method setAccountNumber().

I have a strong suspicion of your intent, but see if my hint there helps you see the issue.

you didn't declare a balance variable but still tried to use it

My setAccountNumber() function is in my BankAccount class, there is no mention of it in the Savings Account class. So now I'm really confused. Are you saying I need to link the classes together somehow?

ok so if im reading ur output right, you forgot a semicolon on line 9 of checking account.cpp. you still havent declared balance. you forgot a semicolon for savings account and you set bankaccount::depositmoney() to void but you still have it returning a value
Fransje (245)

class CheckingAccount //Names the class
class CheckingAccount: public BankAccount

The first line is unnecessary and should be removed.

EDIT: also for the SavingsAccount class.

It's more than unnecessary, it's an error. If it had a semicolon, then it would just be unnecessary...

Start by removing those //Names the class lines and adding a member variable ('balance') to store a balance in the SavingsAccount class. Hint: be sure to initialize balance in the constructor.

OK so I think one of my issues was I had each class as its own base class and not as inherited classes of the base class which in this case is 'BankAccount'. I also found some issues with my functions as pointed out but some of you. Here are the changes that I made...

int transactionCount;



public: //Getter and setter functions.
CheckingAccount();
CheckingAccount(int m, bool display); 
~CheckingAccount(); //Destructor

void withdrawMoney(int m, bool display);
};


I did the same treatment to the checking account and savings account classes. I know I still have the 'balance' not being defined so I am trying to figure out how to correct that. (Instructor gave me a UML to go by). Here is the output now.

OK just as a thread update. I finally was able to make the program compile. I fixed the undeclared identifier 'balance', by renaming 'AccountBalance' to 'balance'. I also added #include BankAccount to the derived classes to define it, and I changed void to double to allow the function to return a value.

Thanks to everyone who chimed in to help me.
