Finding end of file while reading from it

Question

void graph::fillTable()
{
  ifstream fin;
  char X;
  int slot=0;

  fin.open(\"data.txt\");

  while(fin.good()){

  fin>>Gtable[slot].Name;
  fin>>Gtab         


        

Answer 1

Slightly slower but cleaner approach:

void graph::fillTable()
{
  ifstream fin("data.txt");
  char X;
  int slot=0;

  std::string line;

  while(std::getline(fin, line))
  {
    if (line.empty()) // skip empty lines
      continue;

    std::istringstream sin(line);
    if (sin >> Gtable[slot].Name >> Gtable[slot].Out && Gtable[slot].Out > 0)
    {
      std::cout << Gtable[slot].Name << std::endl;
      for(int i = 0; i < Gtable[slot].Out; ++i)
      {
        if (sin >> X)
        {
          std::cout << X << std::endl;
          Gtable[slot].AdjacentOnes.addFront(X);
        }
      }
      slot++;
    }
  }
}

If you still have issues, it's not with file reading...
