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 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.

Hints:

Implement the choices in the menu as functions in your program, even the menu itself.

Arrays should be used.

Your system should use file to retrieve previous data ( if exist) each time it starts. When the user chooses to exit the program, the data should be saved in the same file.
