how to save a whole sentence

[Faggio]

I have this kind of file:

1 hello
2 hello world
3 hello my world


I read this file with getline(file, line) to save, with the use of stringstream, number in a vector of int and the rest of line in a string. The problem is created by the spaces between the words!
Can anyone help me?

Hello Faggio,

Post your code so all can see what you have done and figure what you can do. Otherwise it is just a guess.

If you are using a stringstream I would consider reading the stringstream this way:

ss >> num;

while(std::getline(ss, line, " "))

    fullString += line + " ";

fullString.pop_back();  // <--- Removes last " " (space) 

Untested, but I think it should work.

Hope that helps,

Andy

ok, i can try to post my code but it's little bit complicated.

 while(getline(fin1, line))
   {
       Answer <int> fil;
       is<<line;
       is>>fil;
       is.clear();
       answList.push_back(fil);

}

Note that fin1 is a file, line is a string, fil is a template class, "is" is a stringstream and answList is a list. I have implemented the operator ">>" in the Answer class in this way :

friend istream& operator >>( istream& is, Answer <T> &a)
    {
        is >> a._id;
        is.ignore();
        is >> a._text;
        is.ignore();
        return is;
    }

One way to do it:

int main()
{
  vector<int> numbers;
  vector<string> lines;

  ifstream src("input.txt");
  if (!src)
  {
    perror("ERROR: ");
    return -1;
  }
  int num =0;
  string line;

  while (src >> num)
  {
    numbers.push_back(num);
    getline(src, line);
    lines.push_back(line);
  }
  cout << "Data read:";
  cout << "\n\nNumbers: ";
  cout << "\n--------";
  for (int num: numbers)
    cout << "\n" << num << " ";
  cout << "\n\nLines: ";
  cout << "\n------";
  for (string l : lines)
    cout << "\n" << l << "\n";

  system("pause");
}

If the leading spaces are a problem, you can also add something like this:
line.erase(line.begin(), line.begin() + line.find_first_not_of(' '));

to Thomas1965's worthy code, before
lines.push_back(line);
