1、使用习题12.10屮创建的Account类层次结构开发一个具有多态性的银行系统程序。创建一个Account指针的vector对象，其中的指针指向SavingsAccount对象和CheckingAccount对象。对于该vector对象中每个Account，允许用户使用成员函数debit指定要从Account収出的货币金额，并允许川户使川成员函数credit指定要存入该Account的货币金额。处理每个Account时，应判定它的类型。如果Account是SavingsAccount，就使用成员两数，就使用成员函数calculatel

2、nterest计算该Account应得的利息，然后使用成员函数credit把利息加到帐广余额上。处理完一个Account后，通过调用基类成员函数getBalance打印吏新后的帐户余额。Account.h#ifndefACCOUNT一H#defineACCOUNT_HclassAccount{public:Account(double=0);virtualboolcredit(double);virtualbooldebit(double);virtualdoublegetBalance(){returnbalance;}privat
