I need help with this.

Write a program that calculates the balance of a savings account at the end of a period of time. It should ask the user for the annual interest rate, the starting balance, and the number of months that have passed since the account was established. A loop should then iterate once for every month, performing the following:

1) Ask the user for the amount deposited into the account during the month. This amount should be added to the balance.

2) Ask the user for the amount withdrawn from the account during the month. This amount should be subtracted from the balance.

3) Calculate the monthly interest. The monthly interest rate is the annual interest rate divided by 12. Multiply the monthly interest rate by the balance and add the result to the balance. After the last iteration, the program should display the ending balance, the total amount of deposits, the total amount of withdrawals, and the total interest earned.

PROGRAM AND DOCUMENTATION REQUIREMENTS:

1) The program must be modular. You should have, at minimum, separate modules for each of the following: main, user input, monthly calculations, and output. You may include more if you would like.

2) Include a program analysis worksheet.

3) The program should utilize user friendly prompts and messaging for all interaction with the user.

4) Include a hierarchy chart.

5) Include internal program documentation (comments).

6) Plan the program logic using both pseudocode and flowchart methods.
