Banking System - Problem Description
A bank wants a computer system to help administrator bank accounts. Both checking accounts
and saving accounts must be tracked. Tellers will want to be able to enter an account number
and have all information on the account printed to the screen. The system needs to keep track
of the number of the account, the current balance, and the date that the account was opened.
The savings account has a variable interest rate and the checking account has a monthly
service charge. At the end of each month the balance in each account has to be adjusted. For
the checking account, adjusting the balance involves subtracting the monthly charge from the
current balance. For the savings account, the balance needs to be charged as shown by this
formula.
balance = balance + balance * interest
Finally, the bank needs to be able to find out what the current balance is on the account.

银行系统－－问题描述
银行需要计算机管理银行帐户，包括支票帐户、储蓄帐户。当出纳员输入帐户号码后，屏幕上应输出与该帐户相关的所有信息。系统应记录帐户号码、当前余额、开户日期。储蓄帐户应记录利率，支票帐户记录用户月服务费。在每个月结束时，所有的帐户余额应重新计算并调整。对于支票帐户，计算方法为从当前余额中减去用户月服务费。对于储蓄帐户计算公式如下：
余额＝余额+余额*利率
最后，银行需要知道该帐户的当前余额。
