I write this program to open a text file(example.txt) in a csv(output) file with a variable interval which is another text file (Length.txt). the program was suppose to go through all the lines of the example.txt file but it is stopping after first line. can anyone help me to solve this problem? Please help me.

using namespace std;

int main () {

  ofstream myfile2 ("output.csv");
  int intReturn=0;
  if (myfile1.is_open()&& myfile3.is_open())
  {
      int i=0;
   while (!myfile1.eof())
         {
         getline (myfile1,line);
         
         while (!myfile3.eof())         
            {
            getline (myfile3,line1);
            cout << line1 << endl;         
            intReturn = atoi(line1.c_str());
            word=line.substr(i,intReturn);
            cout << i << endl;
            i=i+intReturn;
            cout << word << endl;
            if (myfile2.is_open())
               {
               myfile2<< word;
               myfile2 << "\n";
               
               }
            }

         }      
         myfile1.close();
         myfile2.close();
         myfile3.close();
  }

  else cout << "Unable to open input file";

  return 0;
