Removing a '\n' from the input file read

How can I remove the extra character which gets taken in when i read the file:

2 3 4 1 6 87 33 9 22 11

Output:2 3 4 1 6 87 33 9 22 11 '\n'

int main() {

      ifstream ifs("input.txt");

      vector<int> data;
      double val;
      while (ifs >> val)
      {
         data.push_back(val);
         cin.ignore('\n');
      }
      for (int i = 0; i < data.size(); i++)
         cout << data[i] <<" ";

      system("pause");
      return 0;
   }
