一、系统功能简介：个人财务收支管理系统可以将日常收入、支出流水保存起来，随时更新、查询收支记录及收支平衡情况。 二、课程设计要求： 1、采用面向对象的方法进行系统分析与设计，利用 UML 类图绘制分析设计结果。 2、按照时间顺序保存收支记录，所有收支记录保存在磁盘文件当中，系统开始运行时从 磁盘读取数据，退出系统时自动将所有数据写入磁盘文件。 3、系统对用户录入的数据具有一定的容错能力，例如，输入的日期为 2023 年 2 月 29 日， 提醒用户重新录入时间。 4、系统有自动提醒功能：当实时收支平衡数额为负数时，发出超支警示；当实时收支平 衡数额达到预期目标时，提示实现财务自由。 5、系统主菜单样例： 1-添加收入记录 2-添加支出记录 3-查看起止日期内的收入记录 4-查看起止日期内的支出记录 5-查看实时收支平衡情况 6-按照日期查找收支记录 7-按照日期修改收支记录 8-按照日期删除收支记录 9-统计起止日期内的各类别收支情况 0-退出系统
程序设计思路定义三个类，分别命名为Date，Fee，Manager，Date类里面含有年月日成员变量以及重载的判断时间的>、} int getyear() { return year; } int getmonth() { return month; } int getday() { return day; } bool operator == (Date b) { if (year == b.year && month == b.month && day == b.day) return true; else return false; } bool operator //同年 if (month > a.month) return false; else if (month //同年 if (month > a.month) return false; else if (month //同年 if (month a.month) return true; else //同月 return day >= a.day; } }};
