活期储蓄账目管理

1、题目：活期储蓄帐目管理活期储蓄处理中，储户开户、销户、存入、支出活动频繁，系统设计要求：能比较迅速地找到储户的帐户，以实现存款、取款记账；并能实现排序能比较简单，迅速地实现插入和删除，以实现开户和销户的需要。#include#include #include#includeusing namespace std;class consumer;class yhpublic:yh();void set_account();/银行开户void del_account();void transfer(int); /转账void enter_account();void addmoney(int,flo
