Have a few errors

[Lauren Buecker]

Outline is fine be me.

[Volatile Pulse]

the first code you posted

void BankingSystem::AddAccount(Account newAccount) {
   // We simply need to add the new account to our vector
   accounts_.push_back(newAccount);
}

Does this go above main?

No, that should go in bankingsystem.cpp. and you will also need to put this in your bankingsystem.h file:

class BankingSystem {
// Some of your code
   public:
   // Some more code
   // This is all that needs added to the bankingsystem.h file
   void AddAccount(Account newAccount);

I think your teacher is introducing too much at one time. The concept of header files and separate source files is a confusing one and not well explained very often. A general rule of thumb is this:
name_of_a_class.h

//#include necessary files

class name_of_a_class {
   private:
      // Put all of the class variables here
      // Notice: they're typically started with a lowercase m or m_
      std::string mName;
      // Some more class variables
   public:
      // Put all of the class functions here
      std::string GetName();
      void SetName(std::string name);
      // Some more class functions
}; // That's all for the .h file 

name_of_a_class.cpp

#include "name_of_a_class.h"

// Now you need to define each of the functions
// Notice: You must use the class name and two : to define the function
std::string name_of_a_class::GetName() {
   // Returns the value of the private variable
   return mName;
}

void name_of_a_class::SetName(std::string name) {
   mName = name;
}

// Other functions contained as well.

// Nothing else should exist here 

main.cpp

// #include necessary header files

#include "name_of_a_class.h"

// Any local function prototypes go here

int main() {
   // Create a new object pointer
   name_of_a_class *myClass = new name_of_a_class();
   // Use the -> operator to dereference the object pointer
   //    and access the public members
   myClass->SetName("Volatile Pulse");

   // Can use them however you need
   std::cout << "myClass's name is: " << myClass->GetName();
}

// Any function definitions typically go here 

Note to self: Pick a better class name next time.

I hope this cleared up the confusion about what should go into each file. I typed that in this editor so it might not be perfect, but should give you a good idea.

[Moschops]

In BankingSystem.h, does your declaration of BankingSystem have the line
void DeleteAccount(string accountNumber); inside it?

[coder777]

From that above the class BankingSystem indeed has no member DeleteAccount but deleteAccount.

C++ is case sensitive.

[TheIdeasMan]

Hi Guys,

Here is my skeleton code, showing how I think the classes should work together.

Again, I have done this because there some confusion in your learning, what you need is an outline so you can see how it all should work.

Some things to note:

The system is all from the point of the bank manager, - there is no input from any customer stakeholder.

See how simple main.cpp is?

The "C" at the beginning of the class names just says that the variable is a class. The is a fairly normal convention - Qt classes start with Q, KDE classes start with K.

The CAccount class is just like a record in a data base, it has a set function and a get function and that's it. All the work is done by the CBank class. You could have a ChangePassWd function. Also note how there is no member variable StartingBalance.

I wrote the CAccount::setDetails functions so that it could also be used by the LoadFile option. The function that does this option can repeatedly call the setDetails function from a loop.

See how the getDetails returns the this pointer - how easy is that!! The InquireAcct function can use the pointer returned to access the members of the CAccount class.

So you can see now what I meant about not needing all those set & get functions, also you can see how almost everything goes in a class. There is very minimal work done by main().

With the CBank class - I had an extra function AuthBM - Authorise Bank Manager's Password - this could be used with an option 0 on the menu - BM Login.

As I said in the comments - I haven't put too much effort into the return types of the functions, maybe you guys can think about that. Try to return something so that the calling function can check that things work.

It would also be easy to write a function that returned the total bank funds - ie the sum of all the acct balances

With ShowMenu & ProcessMenu functions, I put them in main(), because they are for the whole application. As an example, If I were to create a GUI app called MyApp (that looks like a Windows Notepad) using the Qt system, it would have these files:

main.cpp
MyApp.cpp
MyApp.h

Any other classes I invent

main.cpp just runs the app & creates a window frame, not much else
MyApp.cpp creates a TextEdit Control, All the menus & Toolbars, the code that carries out these is in here too.

So the menu is in the main application.

Now, the other way to do things is to have a Menu class, however it is simple as it is now. Would be good for you to create a Menu class, as a learning exercise - after you have go this all working.

Apologies for it taking so long - I had linker problems on my system, then some other dramas to deal with today.

I hope this helps everyone to get a clear understanding - Now you could go on & write the rest of the functions.

So here is the code:
main.cpp

#include <iostream>


#include "CBank.h"

using std::cout;	//this is much better then using namespace std
using std::cin;		//I prefer to do this rather than std:: everywhere
using std::endl;


void ShowMenu();
bool ProcessMenu(const unsigned int MenuOpt, CBank* pCBank, bool
				QuitMenu);

int main() {
	
	unsigned MenuOpt = 0; //The selected Menu Option
	bool QuitMenu = false;
	
	//Create a Bank object
	
	CBank* pCBank = new CBank();
	
	
	
	
	while(!QuitMenu) {
		ShowMenu();
		cin >> MenuOpt;	//haven't done any error checking
		QuitMenu = ProcessMenu(MenuOpt, pCBank, QuitMenu);
	}
    
    return 0;
}


void ShowMenu() {
	cout << "Welcome to My Banking System\n\n" ;
	
	cout << "(1) Add account\n";
	cout << "(2) Delete Account\n";
	cout << "(3) Account Inquiry\n";
	cout << "(4) Save Accounts to File\n";
	cout << "(5) Load Accounts from File\n";
	cout << "(6) Exit\n\n";
	
	cout << "Please Enter your Selection" << endl;
}

bool ProcessMenu(const unsigned int MenuOpt, CBank* pCBank, bool QuitMenu)
{
	switch (MenuOpt)
	{
		case 1:
			//cout << "(1) Add account Option not implemented Yet\n";
			pCBank->NewAcct();
			
		break;
		
		case 2:
			cout << "(2) Delete Account Option not implemented Yet\n";
		break;
		
		case 3:
			cout << "(3) Account Inquiry Option not implemented Yet\n";
		break;
		
		case 4:
			cout << "(4) Save Accounts to File Option not implemented Yet\n";
		break;
		
		case 5: 
			cout << "(5) Load Accounts from File Option not implemented Yet\n";
		break;
		
		case 6:
			cout << "Exiting Program\n";
			QuitMenu = true;
			return QuitMenu;
			break;
			
		default:
			cout << "Invalid selection. Please Choose another option\n";
		break;
		
		
	}

I forgot to put a delete to go with the new CBank in main().

For every object created with new, there should be a corresponding delete (or delete[] for arrays), otherwise there will be memory leaks.

Not a particular problem at the moment, there is only 1 CBank obj (it's destroyed anyway), but is good practice to use delete regardless.

This problem is most noticeable if lot's of objects are being created.

CAccount * CBank::InquireAcct() { //Get all the details of an acct
	cout << "(3) Account Inquiry Option not implemented Yet\n";
}

This part is confusing me...it says that it "must return a value" what about it is causing it to say that?

You are right. My design has a FindAcct function because it needs to be used in several places - so this saves having to rewrite this code every time you want to do something with an account.

The FindAcct function should return a pointer to an CAccount class, so that a function like InquireAcct() can use it to call the relevant get function in CAccount . You might need to have more get functions in CAccount, as you can't access private members via a pointer. The InquireAcct function could be void, or get it to return something so you can check that it worked. As I said n my comments, I hadn't thought about what args or return types functions should have - I was leaving that up to you guys to think abbout.

Can one of you please post the full assignment question?

It's just that if there is action required from the customer stakeholder, this will alter the design a bit. If there are withdraw & deposit functions that are needed, is it going to be a simple system where these just alter the account balance, or do we need to keep transactions & be able to produce bank statements?

The design will alter because we need more functions in CAccount, and we might need a CTransaction class, a CTransactionList class, and a CStatement class. We need to think about how the customer and the Bank Manager are going to interact with the account and each other.

Look forward to your replies.

Project 2

Description: In this project, you will combine the experience from previous assignments and projects to create your largest program. You will also gain experience using vectors, reading and writing files, and formatting output.

Details: Write a program to simulate a simple banking system.

Your first task is to create a class called Account. This class will store a person's account ID, passcode, last name, first name, and balance.

For your second task, you will create a class called BankingSystem. This class must have at least the following functionality:

Add a new account.
Delete an existing account.
Inquire on an existing account (or all accounts).
Save accounts to a file.
Load accounts from a file.

BankingSystem must also use a private data member that is declared as follows:

vector <Account> accounts_;

Your third task will be to develop a driver program. The driver program will print some type of menu allowing the user to choose the option they want. Instead of using a BankingSystem object, you must use a pointer to a BankingSystem object with the new operator. So, in your driver program (int main()), you would write the following:

BankingSystem* myBankingSystem = new BankingSystem();

At the end of your program (end of main() before returning), you have to free this memory explicitly by writing the following:

delete myBankingSystem;

Unlike previous assignments and projects, this one is very open-ended. Besides my explicit requirements, you are free to make your own design decisions. But, remember to use good programming practices such as those pertaining to formatting, commenting, and file organization (i.e. header, implementation, driver).

Programming Tips: This project rolls everything together into one. So, it is important to know the concepts from the previous assignments and projects. It may be helpful to create one function at a time in BankingSystem and test it before proceeding. Remember from the chapter on arrays that a vector is really just a "better" array. Vector's can make life easier than arrays for tasks like searching, adding, and removing items. Another good reference you can find online is http://www.cplusplus.com/reference/stl/vector/. For adding an account, you will find the push_back() function useful. For removing an account, you will find the erase() function useful.

If you would rather not use vectors, which are recommended, they can be substituted using arrays. Due note that arrays cannot grow and shrink as a vector can, so there may be some additional complexity that may prove more difficult.

That said, here are some vector code snippets....

Similar to an array, to create a vector that will store account objects, you'll need to:

vector <Account> accounts_;

If you need more storage in your vector to hold additional account information, you can do so by dynamically creating a new position:

accounts_.push_back( bankAccount );

As with an array, you can iterate through each position of your vector by using the size() function in your for loop. In order to access an object stored in the vector, just use the same indexing method that you'd use for an array.

for( int i = 0; i < accounts_.size(); i++ )
{
bankAccount = accounts_[ i ];

...... Your Code ......
}

Basically, once you come to understand the initial syntax of using a vector, working with them is not that much different that working with an array.

OK, thanks Lauren.

We were posting at the same time.

So there is no involvement from the customer stakeholder.(as per your original description of the problem.)

So ignore all that stuff about transactions etc.

What I was saying about the FindAcct still holds though.


If you have a function in CAccount that prints the details of the account, then you still won't need get functions.

I am interested to hear anyone's comments about the code I posted. I might not have had all the details right, but I hope the layout of what goes where was right.
