Answer:
a. starting balance
Explanation:
A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.
