LabExer#11

11. Develop a program for computing the month-by-month balance in your savings account. You can make one transaction-a deposit or a withdrawal-each month. Interest is added to the account at the beginning of each month. The monthly interest rate is the yearly percentage rate divided by 12.

Use the following formula:
yearlyRate=0.025.
balance = balance+(yearlyRate / 12) * balance
Sample Output:
Enter d for deposit, w for withdrawal or x to exit: d
Beginning of Month Balance: 0.0
Enter deposit amount: 5000
Balance after transaction: 5000.0
Enter d for deposit, w for withdrawal or x to exit: d
Beginning of Month Balance: 5010.416666666667
Enter deposit amount: 3000
Balance after transaction: 8010.416666666667
Enter d for deposit, w for withdrawal or x to exit: w
Beginning of Month Balance: 8027.105034722223
Enter withdrawal amount: 2000
Balance after transaction: 6027.105034722223
Enter d for deposit, w for withdrawal or x to exit: e
Beginning of Month Balance: 6039.66150354456
Balance after transaction: 6039.66150354456
