10.7:

Use the Account class created in Programming Exercize 9.7 to simulate an ATM Machine. Create 10 accounts in an array with the id 0, 1, ... 9, and the initial balance $100. The system prompts the user to enter an id. If the id is entered incorrectly ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Thus, once the system starts, it will not stop.

Example:

Enter and id: 4

Main menu

1: check balance

2: withdraw

3: deposit

4: exit

Enter a choice: 1

The balance is 100.0
