In a bank, there are many accounts. An account can be a normal account or a VIP account.
Account information is stored in a file in the following format (account.txt):
Every account number (accountNo) contains four digits. Password would be a 6-sigits number. For
every account, the client can inquiry, withdraw, save and transfer money. These transactions have
the following features:
1. Withdraw
For normal account, the customer can withdraw at most 2000 per time. For VIP account,
the customer can withdraw 3000 per time. If a customer wants to get money that
exceeds this limit, a warning should be given.

budget in that account, the withdrawal fails. A warning must be given.
