Banking System
This system tracks customers’ accounts in a bank. Each account has a number, name, and balance. The
system provides the following functionalities: create new account, withdraw, deposit, and close account.
The system has the following interface:
Choose:
1- Add new account
2- Withdraw
3- Deposit
4- Get Balance
5- Exit
 When the user chooses 1, the system generates a new ID, and then asks the user to enter a name for
that account. The initial balance is set to zero.
 When the user chooses 2, the system asks the user to enter account ID and amount to be withdrawn. If
this amount is greater than the balance, a message is displayed that this transaction failed because
insufficient balance. If balance is enough, it decreases by amount to be withdrawn.
 When the user chooses 3. The system asks the user to enter account ID and amount to be deposited.
System increases balance by this amount.
 When the user chooses 4, the system asks the user to enter account ID then prints account’s name and
balance.
 Each time a task is completed the system gets back to the main menu above until the user chooses 5.
