Hello! I have written written my own class, which includes a header file and a .cpp file. I have also written the driver for this program. Everything looks fine to me, but I am receiving about 20 random errors. I will post my code for all 3 files but I believe it is a problem that can be diagnosed using just the driver.

The program is a bank account program that adds new accounts, withdraws, deposits, updates, displays, etc. Any help would be greatly appreciated! Thanks.

Hello! I have written written my own class, which includes a header file and a .cpp file. I have also written the driver for this program. Everything looks fine to me, but I am receiving about 20 random errors. I will post my code for all 3 files but I believe it is a problem that can be diagnosed using just the driver.

The program is a bank account program that adds new accounts, withdraws, deposits, updates, displays, etc. Any help would be greatly appreciated! Thanks.

Well, if it's OK with you, we'll just pick 20 random lines and randomly decide they must be wrong. :rolleyes:

Don't you think knowing what the errors are and where the errors are might be helpful in fixing the errors?

And please format your code. It's barely readable without proper indentation.
[edit]I see this has been mentioned at least 4 times. Are you bucking for an infraction? I really hate being ignored, and trying to read more unreadable code. Are you having a problem understanding good formatting guidelines?[/edit]

Sorry...I just thought it might be more obvious to someone else. These are errors that don't make sense to me because they worked before. I have declared what the error says is not and etc. So here are the errors I receive:

Well, for starters in your function prototype for your function find(), you don't have any type values...haven't taken the time to decipher your code to figure out the other problems, but this will solve part of it...

I totally overlooked that. Thank you. I have got it down to one error now. It says that count has an undeclared identifier. I declared it in the addBankAccount function. I tried declaring it before main and passing it as a parameter but I got even more errors. Here is my new code for the driver:

That's because count is only a local variable in your addBankAccount function...As soon as the function ends count goes away...try declaring it at the beginning of main then pass it to your addBankAccount function...you will also have to pass count to your other functions that make use of the count variable...

Ok...I have made those changes and now I have the two errors:

That is because you have the wrong type in the prototype...you are passing acct which is of type BankAccount...therefore you need to change your prototype and header to something like this:

int find(int count, BankAccount accts[], int id);

hope this helps...

Maybe you have to overload the == operator in your bankAccount class definition?

I have already had the HEADER and CLASS DEFINITION approved and we are unable to make changes to them. How could I re-write the Find function so that it cooperates...maybe w/o using Bool?

Like I said before.

if (id == accts[index])

since accts is of bankaccount class you have to overload the == operator. Or do something else.

I don't know how to do that. That's why I was asking if there is an easier way to write it.

I called getID from the Find function but I'm thinking it just overrides the ID I already passed it. The driver compiles, however, none of the functions work properly. Like when I call the deposit function and deposit an amount and then call the display account function the default info is displayed, which is all 0s for balance, interest rate, etc. I don't see anything wrong with the functions and I've been staring at it for a week so I was thinking if someone else looked at it they would spot the problem right away. Here is the new driver code:

    if (found)
        return index;
    else
        return -1;
}

Instead of overloading the == operator you could write an isMatch() method.

Or perhaps you could even do something like.

if (id == accts[index].getID())

//This function displays one bank account.
void displayAccount()
{

   int target;
   cout << "Enter account number.";
   cin >> target;

   accts[target].display();
}

And is that correct do you think? Assuming the account ID's start at 100?

Edited 3 Years Ago by mike_2000_17: Fixed formatting

How would I write an isMatch method? And can you tell why my other functions aren't working as well?

What do you mean? It's incorrect to assume the ID starts at 100? Does it matter since I have initialized that they do?

I can't be asked to explain everything today.

Ready this carefully...there are still errors but it should get you to the next stage.
