cout<<"输入要增加用户的学号"<<" ";

cin>>p1[0].num;

cout<<"输入要增加用户的姓名"<<" ";

水电煤气

cin>>p1[0].name;

cout<<"输入要增加用户的性别"<<" ";

cin>>p1[0].sex;

cout<<"输入要增加用户的年龄"<<" ";

cin>>p1[0].age;

cout<<"请输入要增加用户的身份"<<" ";

cin>>p1[0].status;

cout<<"输入要增加用户的用电量"<<" ";

cin>>p1[0].yongdianliang;

cout<<"输入要增加用户的用水量"<<" ";

（7）输入要删除用户信息

void delet()

{int i;

int flag=0,t;

student *stu=new student[15];

teacher *tea=new teacher[15];

string number;

cout<<"\t输入所删除用户的编号:";

cin>>number;

ifstream f("opq.txt");

for(i=0;i<15;i++)

f>>stu[i].num>>stu[i].name>>stu[i].age>>stu[i].sex>>stu[i].status>>stu[i].yongshuiliang>>stu[i].yongdianliang>>stu[i].meiqiliang;

ifstream F("uvw.txt");

for(i=0;i<15;i++)

F>>tea[i].num>>tea[i].name>>tea[i].age>>tea[i].sex>>tea[i].status>>tea[i].yongshuiliang>>tea[i].yongdianliang>>tea[i].meiqiliang;

for(i=0;i<15;i++)

if(stu[i].num==number)

{flag=1;t=i;break;}

for(i=0;i<15;i++)

if(tea[i].num==number)

{flag=2;t=i;break;}

if(flag==0)

cout<<"\t该用户信息不存在或已删除";

if(flag==1)

{ofstream ma("opq.txt",ios::trunc);

ma.close();

for(i=t;i<14;i++)

stu[i]=stu[i+1];

ofstream m("opq.txt");

for(i=0;i<14;i++)

m<<stu[i].num<<" "<<stu[i].name<<" "<<stu[i].age<<" "<<stu[i].sex<<" "<<stu[i].status<<" "<<stu[i].yongshuiliang<<" "<<stu[i].yongdianliang<<" "<<stu[i].meiqiliang<<endl;

水电煤气

cout<<"\t删除成功";

m.close();

}

if(flag==2)

{ofstream te("uvw.txt",ios::trunc);

te.close();

for(i=t;i<14;i++)

tea[i]=tea[i+1];

ofstream n("uvw.txt");

for(i=0;i<14;i++)

n<<tea[i].num<<" "<<tea[i].name<<" "<<tea[i].age<<" "<<tea[i].sex<<" "<<tea[i].status<<" "<<tea[i].yongshuiliang<<" "<<tea[i].yongdianliang<<" "<<tea[i].meiqiliang<<endl;

cout<<"\t删除成功";

n.close();

}

}

四、运行界面

1.主界面

2增加学生信息界面

3）增加老师信息界面

（4）水电煤气信息的查询

水电煤气

（5）计算并查询用户应缴费用

五、存在问题

1、水平有限，不能够完全的完成全部的功能。

2、程序写的有点复杂。

3、程序之间的衔接不是很好。
