   OpenFileIn(FileIn, FilenameIn);

   OpenFileOut(FileOut, FilenameOut);

   ProcessCustInfo(truth, FileIn);

   OutputCustInfo(FileIn, FileOut);
   return 0;
}

bool ProcessCustInfo(bool& truth, ifstream& FileIn, subscriberInfo& si)
{
   getline(FileIn, si.sn.first, '\n');                   //here
   getline(FileIn, si.sn.last, '\n');
   getline(FileIn, si.sn.custID, '\n');
   getline(FileIn, si.ad.address2, '\n');
   getline(FileIn, si.ad.city, '\n');
   getline(FileIn, si.ad.state, '\n');
   getline(FileIn, si.ad.zipcode, '\n');
   getline(FileIn, si.ri.monthsLeft '\n');        //to here




}



void OutputCustInfo(ifstream& FileIn, ofstream& FileOut, subscriberInfo& si)
{
   if(si.ri.monthsLeft=0)                     //here down to
   {
      FileOut << string(55,'*') << endl;
      FileOut << si.sn.first << " " << si.sn.last << "(" << si.sn.custID << ")" << endl;
      FileOut << sn.ad.address2 << endl;
      FileOut << sn.ad.city << ", " << sn.ad.state <<sn.ad.zipcode << endl;
      FileOut << "The last renewal notice was sent on " <<sn.ri.da.month << " " << sn.ri.da.day << ", " << sn.ri.da.year << endl;          //here
      FileOut << string(55,'*') << endl;
   }
}

我无法弄清楚导致此错误的原因。它发生在所有getline调用的第一个函数中。编译器专门调用第三个，第五个和最后一个，但我很确定所有这些都有问题。

Answer 1

您正在将int类型的变量传递给getline：

getline(FileIn, si.sn.custID, '\n');

这是一个问题。

使用：

std::string custID;
getline(FileIn, custID, '\n');
si.sn.custID = std::stoi(custID);

您遇到同样的问题：

getline(FileIn, si.ad.zipcode, '\n');

和

getline(FileIn, si.ri.monthsLeft '\n');

此外，该行

if(si.ri.monthsLeft=0)

错了。我怀疑这是一个错字。您需要使用==代替=

if(si.ri.monthsLeft == 0)

接收错误＆＃34;没有匹配函数来调用＆＃39; getline（std :: ifstream＆amp;，int＆amp;，char）＆＃39;＆＃34;
