Problem 1. Modify class Account to provide a method called debit that withdraws money from an Account. Ensure that the debit amount does not exceed the Account's balance. If it does, the balance should be left unchanged and the method should print a message indicating "Debit amount exceeded account balance." class AccountTest to test method debit. You can find the Account class template on Canvas.
Note: Refer to "CSC110_Chp3-Classes-v3.ppt" Slides 64-70 to see a sample code
Below is the Sample Output:
account1 balance: $50.00
account2 balance: $0.00
Enter withdrawal amount for account1: 25.67
subtracting 25.67 from account1 balance
account1 balance: $24.33
account2 balance: $0.00
Enter withdrawal amount for account2: 10.00
subtracting 10.00 from account2 balance
Debit amount exceeded account balance.
account1 balance: $24.33
account2 balance: $0.00
