花了九牛二虎之力，
终于找到错了，
主要是 fp2 <<p->REName<<p->REShui<<p->REDian<<p->REMeiqi <<p->REAllmoney<<'\n';
应为： fp2 <<p->REName()<<p->REShui()<<p->REDian()<<p->REMeiqi() <<p->REAllmoney() <<'\n';
他是函数！

虽然虽然这个错误被发现了,但是更错的错误出现拉,主啊......

[w0911h]

楼上所说的是一处，还有一处主要错误是你插入数据的时候写文件有问题

fp2 <<name <<'  ' <<shui <<'  ' <<dian <<'  ' <<meiqi <<'  ' <<allmoney <<'\n';

把上面这句换成下面的，否则写到文件里的内容肯定不是你想要的，" "才表示空格

fp2 <<name <<" "<<shui <<" "<<dian <<" "<<meiqi <<" "<<allmoney << endl;

你有没有照我说的把那句写文件的代码改掉，如果改了，把你原来的文件删掉再重新插入然后再查询

[shirlybaby]

哇,真的可以了,可是问个小问题,如果我要算费用的话应该用什么实现啊.是加在单个的类里面还是别的呢

[/Quote]
你说的费用要怎么算，我看你的程序里已经有了总额

[shirlybaby]

收费标准类，该类存储水电煤气标准单位的收费标准，如：煤气，1.0元/立方米；用水量1.03元/立方米；用电量 0.617元/千瓦时
不同类型人员水、电、煤气信息类，这些类可以包括水表，电表，煤气表ID,抄表时间，上次抄表时间，本次抄表时间，上次抄表度数，本次抄表度数，本次使用度数，费用，是否缴费标记等信息。
这是标准，但是我不知道用什么来实现这个~

[Quote=引用 16 楼 shirlybaby 的回复:]
收费标准类，该类存储水电煤气标准单位的收费标准，如：煤气，1.0元/立方米；用水量1.03元/立方米；用电量 0.617元/千瓦时
不同类型人员水、电、煤气信息类，这些类可以包括水表，电表，煤气表ID,抄表时间，上次抄表时间，本次抄表时间，上次抄表度数，本次抄表度数，本次使用度数，费用，是否缴费标记等信息。
这是标准，但是我不知道用什么来实现这个~
[/Quote]
收费标准应该和具体的用户无关，所以可以单独设计成一个类，其它内容应该都和具体的用户相关，可以放到已经存在的这个类中，当然也可以有其它设计方法，看你想怎么设计了

[shirlybaby]

恩,我再去研究研究撒,谢拉

[别逗我乐]

不同类型人员水、电、煤气信息类。
实现这些类，
声明变量，把它们作为infmation类的成员,编写相应的set get函数用户的数据，同样存放在文件中。
内置的对象的状态比如抄表时间，上次抄表时间，本次抄表时间，依靠infmation传递参数！
