模拟银行卡取款操作，银行卡号为8位，能够进行查询、取款、存款、修改密码等操作。查询时需要输入密码，密码为6位。当密码位数和相应位都符合时，显示卡内余额，否则密码三次错误，结束操作。取款时也需要输入密码，密码为6位。当密码位数和相应位都符合时，显示现有余额，输入取款金额，操作结束显示所剩金额，否则密码三次错误，结束操作。限制每天总共可取的金额 ，若违规给出相应的警告。取款操作时输入取款金额 ，操作结束，显示卡内余额，输入密码时，不显示真实值，修改密码时显示真实值。-simulated bank teller card operation, a registered member of the eight to conduct inquiries, withdrawals, deposits, change passwords operation. Inquiries need to enter a password, the password to six. When the median and the corresponding password-meet, showed the card balance, otherwise the wrong password three times, the end of operation. Teller also need to enter the password, the password to six. When the median and password are consistent with the corresponding position, shows that the existing balance of the amount imported withdrawals, the remaining operation ended shows the amount, otherwise the wrong password three times, the end of operation.
