Using C++, complete the following credit card simulator. Note that this project has already been started, the file is located below the assignment requirements. Please make sure the guidelines below are followed and that the program runs similarly to the sample run as well.

Credit Card Simulator (OOP Principles)
In this assignment you are to create a program to simulate the operations of a credit card (as explained below); the program should be constructed using classes. Account operations include opening the account with an established limit, posting charges and payments, requesting a limit increase, and displaying account history. Data is stored in text files by account number so that you may run the program multiple times with the same account.
A sample/session might be (items in bold are user inputs):
Welcome to the Credit Card simulator!
Existing account or new (E/N): N
Your account number will be: 999999999
Your Credit Limit: $1000.00
Account: 99999999
Outstanding Balance: 0.00
Credit Limit: 1000
Available Credit: 1000
Transaction Options:
0.Quit
1.New Charge
2.Payment
3.Credit Increase Request
4.Card History
Choice: 1
Charge Amount: 100.00
Charge Description: Gas
Account: 99999999
Outstanding Balance: 100.00
Credit Limit: 1000.00
Available Credit: 900.00
Transaction Options:
0.Quit
1.New Charge
2.Payment
3.Credit Increase Request
4.Card History
Choice: 2
Payment Amount: 25
Account: 99999999
Outstanding Balance: 75.00
Credit Limit: 1000
Available Credit: 925.00
Transaction Options:
0.Quit
1.New Charge
2.Payment
3.Credit Increase Request
4.Card History
Choice: 3
Requested Increase: 250
Sorry, but your credit increase cannot be granted at this time.
Account: 99999999
Outstanding Balance: 75.00
Credit Limit: 1000
Available Credit: 925.00
Transaction Options:
0.Quit
1.New Charge
2.Payment
3.Credit Increase Request
4.Card History
Choice: 4
Transaction Log History:
Account 99999999 created, 8/1/2008 10:00:00am
Charge: 100, Gas, 8/1/2008 10:05:00am
Payment: 25, 8/5/2008 4:00:00pm
Limit Increase: 250, declined, 8/6/2008 8:00:00
Account: 99999999
Outstanding Balance: 75.47
Credit Limit: 1000
Available Credit: 924.53
Transaction Options:
0.Quit
1.New Charge
2.Payment
3.Credit Increase Request
4.Card History
Choice: 0
Thanks for using the credit card simulator!
The CREDIT CARD class should handle the normal activities related to a credit card: a) creating the account, b) making charges and payments, and c) updating the credit balance and credit limits. In addition, the Credit Card class will keep account status and transaction histories in text files.
Develop the Credit Card class according to the following guidelines:
1)The class should either create a new account or ‘load’ an old account if a valid account number is given. This would involve 2 constructors: one that takes no account number (and generates a new account) or one that accepts an account number and reads in the current values for the account. In the case of a new account, the Credit Card number should be a randomly generated value while the starting credit limit will be $1000. In the case of an existing account, you must verify that the account actually exists (i.e., there is already a non-empty account status file). The account status (only) data should be stored in a text file named as follows: “CC” + Account Number + “.txt”.
2) Methods for processing transactions must be included. These increase and decrease the credit card balance along with the remaining credit. Make sure that the operator cannot exceed his/her credit limit with any given charge amount. Each transaction should be stored in a credit card log file, with name as follows: “CCL” + account number “+ “.txt”
3)Allow for a request for a credit increase; increases are granted in $100 increments. Use a random number generator to determine whether a credit increase request is granted or denied.
4)The display of the transaction log is to be done in the ‘view’ program (the program with main()) – there should not be any screen output done by the Credit Card Class. Each transaction log entry is time-stamped when posted to the file (as seen from the sample run).
A list of likely class properties for the Credit Card Class:
- 2 Constructors (with and without Account number);
- account number (returns current account number);
- credit limit (returns current limit);
- credit increase (returns code indicating success/failure of increase request);
- available credit (return value);
- balance (return value);
- transaction (processes transactions and returns error status codes);
- history log (returns an appropriate structure containing account history)
Other class members may be created as you see fit.
