    I am having trouble with one of my school assignments. If someone can please help me with my errors I would be extremely happy! I will include my assignment, the 3 files(it’s a class) and the errors. If you need me to I can zip these filed and attach them!


    1. You are a programmer that works for a local bank. You are creating classes to be used in the class library for this bank for all of its programs. You will also create a main() to test your new classes.

    Talking to the bank manager you find out that the two main problem domain objects (“things” in our system we need to keep track of) are “Accounts” and “Customers”. You find out that customers have accounts, and that a customer can have more than one account (of different types like checking, savings, or overdraft/credit card.) Accounts are thought of as being distinct objects and should never be separated from the Customers that they are a part of.


    Customer Class (20 points):
    Attributes/data members:
    name (a string)
    ssn (a string)
    address (a string)
    birthdate (a Date)
    savings (an Account)
    checking (an Account)

    Behaviors/member functions:
    1) accessor (get) and mutator (set) functions for all attributes.
    2) DisplayCustomer(), this function should show a message on the console with the customer’s name, ssn, and the balances for each account.

    Constructor(s):
    This class must have a constructor that accepts all of the data to create a Customer and initializes its data members.

    Date Class:
    (This class is from your company’s current class library. See separate file for the date class. It is from page 714 in your book.)

    Account Class (20 points):
    Attributes/data members
    number (an integer)
    type (a string)
    balance (a double)
    rate (a double)

    Behaviors/member functions:
    1) accessor (get) and mutator (set) functions for all attributes.
    2) ApplyInterest(), this function should take the balance and multiply it by the rate to find the interest this period…then add it to the existing balance.

    Constructor(s):
    This class must have a constructor that accepts all of the data to create an Account and initializes its data members.

    Validation in member functions/ Business Rules:
    1) Rates should be between .01 and .10 (it is an interest rate as a decimal)
    2) Balances should never be allowed to be set to a negative value.


    2. (15 points)Add operator overloading to the Account class to allow the +, -, /, and * operators to be used to do mathematical calculations between two accounts.

    Change the Customer class DisplayCustomer() function to show the consolidated balance as well. Create a temporary account and set it equal to savings + checking (using the overloaded + operator), then report its balance as the consolidated balance (or total balance if you prefer to call it this.)

    3. (9 points)Create statements in main() to test your new classes.

    1) Create two new customers in your program (with all their data.)

    2) Display the customer information for your two customers using the DisplayCustomer() function.

    3) Call the ApplyInterest() function to apply the interest for the current period.

    4) Display the customer information for your two customers again using the DisplayCustomer() function.

    i dont think that you can overload constructors, but you can set defaults for variables in the parameter list.

    add default values for your parameters in a single constructor like this:

    Code:
     
    public:
        Account(string, int, double, double) {
            void setType(string);
            void setNumber(int);
            void setBalance(double);
            void setRate(double);
            string getType();
            int getNumber();
            double getBalance();
            double getRate();
            void valid_Rate(double);
            void ApplyInterest();
        };
    //-----------------------------------------------------------------------------
    //class definition
        Account::Account(string type = "", int number = 0, double balance = 0, double rate = 0) 
    {
            Account::type = type;
            Account::number = number;
            Account::balance = balance;
            valid_rate(rate);
    }
    
    test it by not assigning any values to the constuctor call... just to be sure :)

    oh wait...duh... you can overload constructors, but you dont need to define the default constructor in your definition list. only define the constructors that take parameters.

    here is an example:
    http://www2.cs.uregina.ca/~saxton/CS115/Notes/Overloading/overload.html

    like this:

    Code:
     
    //Account Class
    class Account {
    private:
        Customer myCustomer[2];
        string type = "";
        int number = 0;
        double balance = 0;
        double rate = 0;
        double intrest;
        double NewBalance;
    public:
        Account(); // Default Constructor
        Account(string, int, double, double) {
            void setType(string);
            void setNumber(int);
            void setBalance(double);
            void setRate(double);
            string getType();
            int getNumber();
            double getBalance();
            double getRate();
            void valid_Rate(double);
            void ApplyInterest();
        };
    //-----------------------------------------------------------------------------
    //class definition
        Account::Account(string type, int number, double balance, double rate) 
    {
            Account::type = type;
            Account::number = number;
            Account::balance = balance;
            valid_rate(rate);
     }

    i think i might have led you astray.

    in your public declaration of Account, you were actually defining the constructor. thats why you were getting the "already defined" errors.

    try this:

    Code:
     
    //Account Class
    class Account {
    private:
        Customer myCustomer[2];
        string type;
        int number;
        double balance;
        double rate;
        double intrest;
        double NewBalance;
     
    public:
        Account(); // Constructor
        Account(string, int, double, double); 
     
        void setType(string);
        void setNumber(int);
        void setBalance(double);
        void setRate(double);
     
        string getType();
        int getNumber();
        double getBalance();
        double getRate();
     
        void valid_Rate(double);
        void ApplyInterest();
    };
    //-----------------------------------------------------------------------------
    //class definition
        Account::Account() 
    {
            type = " ";
            number = 0;
            balance = 0;
            rate = 0;
     }
     
        Account::Account(string type, int number, double balance, double rate) 
    {
            Account::type = type;
            Account::number = number;
            Account::balance = balance;
            valid_rate(rate);
    }

    ok... you have alot of typos.

    see the problems? this is just a few of them.

    Code:
     
    void valid_Rate(double);
     
    Account::Account(string type, int number, double balance, double rate) 
    {
        Account::type = type;
        Account::number = number;
        Account::balance = balance;
        valid_rate(rate);
    }
    

    Code:
     
    void ApplyInterest();
     
    void Account::ApplyIntrest() {
       intrest = rate * balance;
       NewBalance = intrest + balance;
       cout << "The amount of intrest for the Customer is: $" Account::interest << " and the account balance is: $" << Account::NewBalance << ".\n";
    } 
    

    Code:
     
    double intrest;
     
    void Account::ApplyIntrest() {
       intrest = rate * balance;
       NewBalance = intrest + balance;
       cout << "The amount of intrest for the Customer is: $" << interest << " and the account balance is: $" << NewBalance << ".\n";
    }

    your overloaded increment and decrement functions dont have protopyes in your class definition.

    also, your overlaoded functions are referencing variables that have not been declared in the class definition.

    huh?? I am knew to this! You are going to have to give me an example. The teacher gave us the code with no comments so its hard to tell what everything does!

    these definitions need to be declared in your class:

    Code:
     
        void operator += (Account& a) {
            setBalance(balance + a.balance());
        }
        void operator -= (Account& a) {
            setBalance(balance - a.balance());
        }
        void operator ++ (int n) {
            Customer::balance(Customer::savings + Customer::checking);
        }
    

    the variables (savings and checking) are not declared in your class.

    here is an example of overloading operators:

    i dont see the variables checking or savings declared here:

    Code:
     
    //Account Class
    class Account {
    private:
            Customer myCustomer[2];
            string type;
            int number;
          double balance;
          double rate;
            double intrest;
            double NewBalance;
     
    ......
    ......
     
    };
    

    you also need to add these declarations to your public class definition:
    void operator += (Account&);
    void operator -= (Account&);
    void operator ++ (int);


    also take out the comma in the parameter list here:
    Code:
     
        void operator ++ (int n, ) {
                    Customer::balance(Customer::savings + Customer::checking);
        }

    i think you may need to start your projects sooner and maybe seek help sooner :)
