Question

There is a problem in BankAccount class. There is a problem with Deposits and Withdrawals. Step through the program via the Debugger and determine what and where the problem is. Then comment out the bad code and put in new code to fix the problem, and add a comment above your change.

The ending Balance should be: $5.51

Starting balance = $100
Total of Deposits = $70 (added to balance)
Total of Withdraws = $162 (subtracted from balance)
Interest made = .01 (rounded from 0.01375) (added to balance)
Service Charge = $2.50 (subtracted from balance)
