Question

Design a program that will serve as a database for keeping track of a student’s checking account and its history. This application will allow for the entering of checks (payee, date, amount, check number) and the entering of deposits (date and amount) and store that information into a database (text file). The application will also need to be able to retrieve that information based on data that is to be input by the user of the program.
Your program should be interactive, presenting the user with a menu of choices, such as the following:

1. Enter Deposit
2. Enter Check/Withdrawal
3. Search for Check by Payee
4. Search for Checks Written in a Particular Month
5. Show a Listing of All Checks Written/Deposits Made
6. Display Current Checking Balance
7. Save Register to a file
8. Load Register from a file
9. Exit

Here is a brief explanation of what I am looking for to be contained with each menu item:

1. Enter Deposit. The user will be able to enter information pertaining to a deposit to the checking
account. You should ask the user for the date and the amount of the deposit. Either this option, option 2, or option 8 must be done before 3, 4, 5, 6, or 7 can be chosen.

2. Enter Check/Withdrawal. The user will be able to enter information related to a check that is written from the account. The user will need to enter the name of the Payee, the date the check is written, its amount, and the check number. Either this option, option 1, or option 8 must be done before 3, 4, 5, 6, or 7 can be chosen, meaning you must prevent a user from trying options 3, 4, 5, 6, or 7 until option 1, 2 or 8 has been chosen.

3. Search for Check by Payee. This option will prompt the user for a payee’s name (ie., Brian M Morgan) and return any information on checks written to that person. If there have been not been any checks written to that particular payee, a message stating this fact should be displayed. Information that should be displayed if a match exists for a given payee would include all of the check’s information entered in option 2. NOTE: Your program should not allow the user to do #3 unless #1, #2 or #8 has been performed at least once. The output format should resemble that of what is on the next page:
Check # Payee Date Amount
1005 Brian M Morgan 4/17/2009 ($300.15) 2132 Brian M Morgan 1/17/2010 ($ 68.13)

4. Search for Checks Written in a Particular Month. For this option, your program will output the details for checks written during a particular month (includes month and year, ie February 2010). This output will consist of a table similar to the one above. NOTE: Your program should not allow the user to do #4 unless #1, #2 or #8 has been performed at least once.

5. Show a Listing of All Checks Written/Deposits Made. This option will produce a similar listing to the one in option 3 above, but will simply list every single check and deposit made and its corresponding data. Deposits are shown WITHOUT the () around the amount. It is typical to show withdrawals (negatives) with the (). NOTE: Your program should not allow the user to do #5 unless #1, #2 or #8 has been performed at least once.

6. Display Current Checking Balance. For this option, your program will calculate and output the current balance of the checking account. NOTE: Your program should not allow the user to do #6 unless #1, #2 or #8 has been performed at least once.

7. Save Register to a file. All of the entered data should be written to a data file (plain .txt file is ok) in a format so that it is easy to retrieve later (see below). You must prompt the user for the name of the file.

8. Load Register from a file. Data will be read back into your program from a previously saved data file. You must prompt the user for the name of the file.

9. Exit the program gracefully, including closing all files.
