ファイルを読み込んでいるときにエラーが発生しました。代替データを格納している間にエラーが発生しました。

Question

これは私のコードです。クラスに保存しなければならない行を読み込んでいて、次の行の値を格納しています。コードの誤り。それを修正するのを手伝ってください。タスクは、文を持つ行をスキップし、データを持つ行を読み込み、それをクラス変数に格納することです。

#include <stdio.h> 
#include <iostream> 
#include <fstream> 
#include <sstream> 
#include <stack> 
#include <string> 

using namespace std; 

class data_Read 
{ 
public: 
    /* timestamp */ 
    double time; 

    /*state of the signal 1 or 2*/ 
    unsigned int state; 

    /*ID in hexadecimal and converted to decimal*/ 
    std::string ID; 

    /* Received or transmitted message */ 
    std::string status; 

    /* Message type */ 
    std::string type; 

    /* byte length */ 
    unsigned int byte_lent; 

    /* CAN Message */ 
    std::string message_1; 
    std::string message_2; 
    std::string message_3;

Answer 1

the final answer 

while (std::getline(file, line)) 
    { 
     std::istringstream iss(line); 

     std::size_t space = line.find(" ", 0); 
     if (!isspace(line[0])) 
     { 
      iss.clear(); 
     } 
     else 
     { 
      int i; 
      for (i = 0; i <= 12; i++) 
      { 
       if (isalpha(line[i])) 
       { 
        iss.clear(); 
        goto start; 
       } 
      } 

      iss >> data.time >> data.state >> data.ID >> data.status >> data.type >> data.byte_lent >> data.CAN_message_1 >> data.CAN_message_2 >> data.CAN_message_3 >> data.CAN_message_4 >> data.CAN_message_5 >> data.CAN_message_6; 
      iss >> data.CAN_message_7 >> data.CAN_message_8 >> data.type1 >> data.type2 >> data.type3 >> data.type4 >> data.type5 >> data.type6 >> data.type7 >> data.type8 >> data.type9;
