C++银行账户管理系统

1、个人银行账户管理系统设计要求设计一个个人银行账户管理程序，能够显示帐户信息、存款、取款、余额、结算利息等操作。要求：个人根据实际能力进行设计，可以在基本功能的实现的前提下尽可能充实完善自己的程序。设计思想1、类的结构图Saving-id:int-balanee：double-lastDate:int-rate:double-aeeumulation:double-accummulate:(date:int):double+saving(date:int,int:id,rate:double);+getid():intjisuan(date:int,amount:double);+getbala

2、nce():double+cunru(date:int,amount:double);+quchu(date:int,amount:double);+getrate():double+lilv(date:int);+show()2、程序主要功能说明功能说明：首先输入开户的时间，开户账号，银行的利率来创建一个账户，选择一个日期(可以是开户时，也可以是开户的X天后)存入一笔钱，然后再在存款的X天后，取岀一笔钱。取岀后，系统会自动计算，从存款的那天到取款的那天之间的本金和利息之和；用户还可以计算若干天后的利息和本金之和；三、源代码#include<>#include<cmath&g
