You have been asked to create a program for a Bank to process a set of transactions (i.e., deposit and withdraw) against a set of accounts, and produce a statement for each account. Input to the program will be two files one containing a list of accounts and the other a list of transactions. On file is text the other binary. Output will be a report to standard out. The format of each file is as follows:

Accounts.txt a text file containing a set of records in a csv format. Each record represents an account. The format of a record is:

Fields

Description

Account number

Digits

First name

String of characters

Last name

String of characters

Balance

Digits with decimal point and two fractional digits

Transactions.dat a binary file containing a set of records. Each record represents an account. The format of a record is:

Fields

Description

Account number

4 byte twos complement

Date

1 byte twos complement for month, followed by 1 byte twos complement for day, followed by 2 bytes twos complement year

Type

1 byte ASCII either D for deposit or W for withdraw

Amount

Double precision floating point

In addition, the program is to output the updated accounts to a new file in the same format as the input.

Your program must pass the file names on the command line. In the event the files are not passed on the command line, then ask the user to enter the file names for the accounts, transaction, and new accounts files. Using those files, the program will process the transactions, print the statement report and write the new accounts file. A sample output of the statement report is as follows:
