My problem with getline()

I dont know if i did it right to make a new thread, because this is the same program
but another problem.

I got a problem with istream::getline.
If i use it without the delimiting character its gonna read the whole file so i cant compare word by word the 2 files.
If i use the delimiting character ' ' space, it wont take in consideration neither the last word of every line ,
because there is know 'space' after it, nor the first word of every line, because there is no 'space' before it.
Maybe i should use another function like read() or something?
Thanks for any input on this.

Code:

                       
int main ()
{
  vector<string> vWords1;
  vector<string> vWords2;
  
  read_file("1.txt", vWords1);
  read_file("2.txt", vWords2);
  
  sort (vWords1.begin(), vWords1.end());
  sort (vWords2.begin(), vWords2.end());
  
  vector<string> v;
  
  set_intersection (vWords1.begin(), vWords1.end(), vWords2.begin(), vWords2.end(), back_ inserter(v));
  
  cout << "Intersection has " << v.size() << " elements.\n";
  for (size_t i = 0; i != v.size(); ++i)
    cout << "The "<< i+1 <<"." << " element is: " << v[i] << "\n";
  
  system("pause");
}
  void read_file(const char* name, vector<string>& vWords)
  {
    ifstream file(name);
    string line;
    vWords.clear();
    while (getline(file, line, ' ')) {
        vWords.push_back(line);
    }
  }

If the words are separated by whitespace (spaces, tabs or newlines) then don't use getline, use operator >>.

Wow, that was simple. I didnt know we could use oparator>> with fstream. *me ashamed*

Thank you Daved!
