getline（）和向量（C）的问题

我正在尝试从文本文件中获取输入，并使用getline（）将数据放入四个向量中 . 该文件包含两个字符串，一个double和一个整数，全部在不同的行上，每个组由一个空行分隔 .

if (userChoice == 1) // Load
            {
                in_stream.open("Lab11.txt");
                if (in_stream.fail())
                {
                    cerr << "File does not exist" << endl;
                    system("PAUSE");
                    exit(1);
                }
                index = 0;
                do
                {
                    getline(in_stream, itemNumb[index]);
                    getline(in_stream, itemName[index]);
                    getline(in_stream, itemCost[index]);
                    getline(in_stream, itemQuant[index]);
                    index++;
                } while (! in_stream.eof());
                in_stream.close();
                itemStored = 0;
                cout << "Items stored: " << itemStored << endl;
            }

itemNumb和itemName是字符串向量，itemCost是double，itemQuant是整数 . 字符串的行不会产生错误，但double和整数的行会产生相同的错误，类型会根据它的向量而变化 .

Error:

没有用于调用getline的匹配函数（std :: ifstream＆，double＆）'|

编辑的文件行io，导致运行时错误

do
    {
        getline(in_stream, tempstr1);
        itemNumb.push_back(tempstr1);
        getline(in_stream, tempstr2);
        itemNumb.push_back(tempstr2);
        in_stream >> tempdoub;
        itemCost.push_back(tempdoub);
        in_stream >> tempint;
        itemQuant.push_back(tempint);
        index++;
    } while (! in_stream.eof());
    in_stream.close();
