Homework #9

Assigned April 4, due April 11 at 11:59 PM

This homework assignment gives you the opportunity to practice structures, classes, dynamic array creation, use of overloaded operators.

HW9 (Graded out of 100)

Your program will read from an input file that contains account records. Each account record starts with a delimiter, which is the '#' character, followed by the account number, followed by the number of owners, followed by one or more owner records (there is one record for each owner), followed by the number of transactions, followed by one or more transaction records (there is one record for each transaction). An owner record consists of the owner's name followed by the owner's DOB in mm/dd/yyyy format, followed the owner's address. A transaction record consists of the transaction date, followed by the transaction type (1 for account creation, 2 for deposit, and 3 for withdrawal), followed by the amount. The various fields are separated by a white space, except for the owner's name and address, which are surrounded by a new line. Below is an example of account record. The // comments are added for clarification, but are not part of the file content.

#

1200 // account number

2 // number of owners

Kirk // owner's name

02/12/2200 // owner's DOB

Enterprise // owner's address

Mr. Spock // owner's name

03/13/2300 // owner's DOB

Galaxy Way // owner's address

2 // number of transactions

02/15/2320 3 100 // first transaction record

02/11/2320 1 200 // second transaction record

Your program should determine the number of account records in the file, dynamically create an array of Account of size equal to the number of account records (note this is an array of Account, not an array of pointers to Account), and populate the array with the data read from the file. Finally it should display for each account, the owner's data and the transactions data sorted according to their dates (the oldest transaction should be listed first).

Your program should implement the following:

Date class

This class is as defined in HW8, implement in-line in Date.h

Account class

This class is adapted from HW7. The additions with respect to HW7 are underlined. Implement in-line in Account.h

struct Transaction

Date transactionDate; int type; double amount;

};

struct Person {

string name; Date DOB; string address;

};

The class Account has the following private member variables:

accountNumber of type int numOwners of type int ownerPtr of type Person * balance of type double

numTransactions of type int // Number of transactions for the account

transacPtr of type Transaction * // Pointer to an array that holds the Transactions

and the following public member functions:

void setOwner(int, Person): as in HW7 Person getOwner(int) const: as in HW7 int getAccountNumber() const: as in HW7 double getBalance() const: as in HW7 int getNumOwners() const: as in HW7

The public member functions new with respect to HW7 are defined as follows.

void set(int accountNumber , int numOwners ) : mutator that sets the accountNumber and numOwners, dynamically creates an array of Person of size numOwners, and assign to ownerPtr. Sets balance to zero.

void setTransacPtr(Transaction * transacPtr ) : mutator that sets transacPtr to transacPtr int getNumTransactions() const: accessor for numTransactions

void setNumTransactions(int numTransactions ) : mutator that sets numTransactions to numTransactions

Transaction getTransaction(int ind) const: accessor that returns the Transaction at index ind of the transacPtr array

Stand-alone Functions (in main.cpp)

You should implement the following stand-alone functions.

/* This function takes as argument a string representing a date in the mm/dd/yyyy format and returns the month as an int

The argument string is assumed properly formatted and no input validation is required */

int getMonth(string d)

{

// Function body

}

/* This function takes as argument a string representing a date in the mm/dd/yyyy format and returns the day as an int

The argument string is assumed properly formatted and no input validation is required */

int getDay(string d)

{

// Function body

}

/* This function takes as argument a string representing a date in the mm/dd/yyyy format and returns the year as an int

The argument string is assumed properly formatted and no input validation is required */

int getYear(string d)

{

// Function body

}

/* This function reads from an account file and populates an array of Account objects (not an array of pointers to Account) with all the owners and transactions data read from the file. The owner data is the owner's name, DOB and address. The transaction data is the transaction date, transaction type (account creation, deposit, withdrawal), and transaction amount. For each account, the function should dynamically allocate an array of Transaction of size equal to the number of transactions, assign the array's address to transacPtr, and populate the array with the transaction data. In the array, the transactions should be sorted by date (oldest first).

It takes as arguments the file name, the array and the size of the array.

It returns true if file open is successful, false otherwise. It should close the file when done */

bool readAccounts(string fname, Account accntPtr [], int numAccnts)

{

// Function body

}

/* This function reads from a file to determine the number of accounts It returns -1 if file open is unsuccessful, else it returns the number of accounts */

int determineNumAccounts(string fname)

{

// Function body

}

Outline of main

Call determineNumAccounts to determine the number of account records in the file

Dynamically create an array of Account of size equal to the number of accounts, to hold the Account objects (note this is an array of Account, not an array of pointers to Account),

Call readAccounts to read data from the file and populate the array of Accounts.

Read the populated array of Accounts to display for each account the account number, along with the data for all the owners, and the data for all the transactions. The owner data is the owner's name, DOB and address. The transaction data is the transaction date, transaction type (account creation, deposit, withdrawal), and transaction amount. Additionally, the new balance resulting from each transaction is displayed. The transactions should be listed by date, the oldest transaction being listed first.

Additional Requirements

What to turn in

main.cpp

Date.h - All the member functions of Date are in line

Account.h - All the member functions of Account are in line

Style

Make sure you follow the style requirements, especially regarding the comment header for functions, to avoid losing points.

Suggestions for implementation

a) Read data from file

You may assume the data records in the file are properly formatted (no need to do input validation)

Assuming inFile is your file stream object, inFile >> .... will read the date like cin >> ....That is, it will leave a left over new line character in the buffer. To flush the left over character from the buffer, you can use inFile. ignore () , which works similarly to cin.ignore() .

getline(inFile, ... ) will read the data like getline(cin, ... ). That is, it will read the whole line (including spaces) until a new line is found.

You may assume the transactions in the file are a log of past transactions which have been actually executed, and for which there was no error such as excessive withdrawal amount, negative deposit amount, incorrect account number, etc.

b) Sorting of Transaction

You will need to sort the Transaction according to their dates. You may adapt the bubble or insertion sort algorithms, and use the overloaded < operator for Date.

Expected Output

Use the "f.txt" file to test your program.
