Question

不会C++啊，就要考试了，怎么办，求高高高人帮帮忙啊，帮忙翻译一下以下代码没一句是什么意思，多谢了～～

void Employee::DeleteInfo() //删除员工数据的函数
{ char tmp;
int cNum = 1000;
DBOperate dbo;
dbo.ReadOut();
void Employee::shownum(long number);

cout<<"请输入您要修改的员工编号>： ";
cin>>cNum;
int MN;
MN = Employee::MaxNum();

for(int i=0;i<MN;i++) //遍历数据文件，查找要删除的员工
{
if(Enum[i] == cNum)
Employee::shownum(cNum);
}

cout<<"确认要删除该员工信息？(Y为确认 N为放弃)： ";
cin>>tmp;
if(tmp=='Y')
{
if(i==MN-1)
dbo.WriteIn(-1);
else
{
for(int j=i;j<MN-1;j++)
{ Enum[j] = Enum[j+1]; }
dbo.WriteIn(-1);
}

cout<<" 删除操作成功 ! "<<endl;
}

}

float Employee::Pay(int Employeeposition) //根据员工职位计算工资的函数
{
float tmpPay;
tmpPay = Employee::EmployeeBasePay + Employee::Employeeposition * Employee::EmployeeBasePay;
return tmpPay;
}

void DBOperate::WriteIn(int iflag) //数据操作函数 写入
{
DBOperate::RefreshMaxNum(iflag);
ofstream myf("Employee.txt");
Employee e;
int MN;
MN = e.MaxNum();
for(int i=0;i<MN;i++)
{
myf<<Enum[i]<<'\n'<<Ename[i]<<'\n'<<Esex[i]<<'\n'<<Eage[i]<<'\n'<<Emarriage[i]<<'\n'<<Edegree[i]<<'\n'<<Edepart[i]<<'\n'<<Eposition[i]<<'\n'<<Eworktime[i]<<'\n'<<Epay[i]<<'\n';
}
myf.close();
return;
}

void DBOperate::ReadOut() //数据操作函数 读出
{
ifstream myf("Employee.txt");

Employee e;
int MN;
MN = e.MaxNum();
for(int i=0 ;i<MN;i++)
{
myf>>DBOperate::Employeenum>>DBOperate::Employeename>>DBOperate::Employeesex>>DBOperate::Employeeage>>DBOperate::Employeemarriage
>>DBOperate::Employeedegree>>DBOperate::Employeedepart>>DBOperate::Employeeposition>>DBOperate::Employeeworktime>>DBOperate::Employeepay;

Enum[i] = DBOperate::Employeenum;

}
myf.close();
}

void DBOperate::RefreshMaxNum(int iflag) //更新系统中员工计数文件的函数
{
int MaxNum = 0;
ifstream myif("EmployeeMaxNum.txt");
myif>>MaxNum;
myif.close();
MaxNum = MaxNum+iflag;
ofstream myof("EmployeeMaxNum.txt");
myof<<MaxNum;
myof.close();
}

Answer 1

嗯，就是得慢慢看，不难。变量命名都挺好的。学习。

Answer 2

倒是蛮简单的，就是太长，太耗时了。
