我正在尝试在virtual void BillRecord::ReadCustDetails(ifstream &fin)中读取包含客户详细信息的文本文件。代码工作正常但我不知道如何读取整个地址和负值并将它们存储到私人成员。我尝试了以下代码,但输出错误。

文本文件:

我的输出:

必需的输出:

  public:
    BillRecord();
    virtual void ReadCustDetails(ifstream &fin);
  private:
    BillType BType;
    string Supplier; // Supplier's name
    string Name, Address; // Customer's name and address
    double BillAmount;// Amount in dollars and cents of this bill            
    int DaysSinceLastReading; // Days since last reading

};

 virtual void BillRecord::ReadCustDetails(ifstream &fin)
 {
        fin >> Supplier;
        getline(fin,Name);
        getline(fin,Address);
        fin >>AccountBalance;
        fin >>BillAmount;
        fin >>DaysSinceLastReading;
        fin >>i;
        DaysSinceLastReading=i;

    //put the code here for reading the customer details part of the file 
record only into the private data members

cout << Supplier<< endl;
cout << Name  << endl;
cout << Address << endl;
cout << BillAmount << endl;
cout << AccountBalance << endl;
}

您的代码仅有一些小问题。尝试更具体。除了此代码,真正的问题是什么?您必须在其他功能上遇到问题。尝试将它们张贴在这里。我已经尽力修复了。

void BillRecord::ReadCustDetails(ifstream &fin)
{

fin >> Supplier;
fin.ignore();
getline(fin,Name);
getline(fin,Address);
fin >> BillAmount;
fin >> AccountBalance;
fin >> DaysSinceLastReading;
cout << DaysSinceLastReading;

cout << Supplier << setw(16);
cout << Name     << setw(27);
cout << Address  << setw(15);
cout << BillAmount << setw(14);
cout << AccountBalance     << setw(8);
cout << DaysSinceLastReading  << setw(6);
}
