Short Answer

Expert verified
Question: Create a hierarchy chart or a flowchart for a program that calculates the current balance in a savings account, taking into account user inputs, the calculation of the current balance, and the output display.

Step by step solution

01

Start

Draw the start symbol to initiate the flowchart.
02

Get Input

Draw the input symbols to represent the user prompts, acquiring: 1. The starting balance 2. The total dollar amount of deposits made 3. The total dollar amount of withdrawals made 4. The monthly interest rate
03

Compute New Balance

Use a process symbol to describe the calculation of the current balance using the following formula: Current Balance = Starting Balance + Deposits - Withdrawals
04

Calculate Interest

Using a process symbol, calculate the interest amount to be added to the current balance. The formula for interest calculation is: Interest Amount = Current Balance * Monthly Interest Rate
05

Update Current Balance

Use another process symbol to add the calculated interest amount to the current balance. The formula for updating the current balance is: Current Balance = Current Balance + Interest Amount
06

Display Output

Draw the output symbol to represent the display of the current balance on the screen.
07

End

Draw the end symbol to indicate the completion of the flowchart.
