Problem #29 - Using Files - Savings Account Balance Modification

Modify the Savings Account Balance program described in Programming Challenge 25 so that it write the report to the file. After the program runs, print the file to hand in to your instructor. (You don't need to print it...it should be found on the linux server.)

Saving Account Balance program #25

Write a program that calculates the balance of a savings accont at the end of a three-month period. It should ask the user for the starting balance and the annual interest rate. A loop should then iterate once for every month in the period, performing the following steps:

A) Ask the user for the total amount deposited into the account during that month and add it to the balance. Do not accept negative numbers.

B) Ask the user for the total amount withdrawn from the account during that month and subtract it from the balance. Do not accept negative numbers of numbers greater than the balance after the deposits for the month have been added in.

C) Calculate the interest for that month. The monthly interest rate is the annual interest rate divided by 12. Multiply the monthly interest rate by the average of that month's starting and ending balance to get the interest amount for the month. This amount should be added to the balance.

After the last iteration, the program should display a report to the screen and (to a file) that includes the following information:

*starting balance at the beginning of the three-month period

*total deposits made during the three months

*total withdrawals made during the three months

*total interest posted tot he account during the three months

*final balance
