    //写文件
    ofstream outFile; //ofstream outFile("file.csv", ios::app);
    outFile.open("file.csv", ios::app); //“file.csv” 文件名; ios::app  末尾追加模式 out/in/...

    outFile << "name" <<"," << "age"<> strAry;
    while(getline(inFile, lineStr))

        //存成二维表结构
        stringstream ss(lineStr);

        //按照逗号分隔
        while(getline(ss, str, ','))
            lineAry.push_back(str);
        strAry.push_back(lineAry);
    }
    
    getchar();
    return 0;
