Problem inputting numbers into vector from file

Hello! so, I'm implementing quicksort and selection sort using vectors.
I have the following code. To run I use redirection. i.e. ./program.out <datafile

Code:

int main()
{
  int number;
  vector<int> list;
  cout << "QuickSort..." << endl;
  while (cin >> number)
    {
      list.push_back(number);
    }
  int left = 0;
  int size = list.size();
  int right = size-1;
  print(list); // testing sort
  quickSort(list, left, right);
  print(list); // testing sort
  cout << "Done" << endl;

  return 0;
}

But my vector seems to be empty?
I've changed the while loop to

Code:

cin >> number;
while (!cin.eof())
{
  list.push_back(number);
  cin >> number;
}

That gives me a bad_alloc error though.

Any tips? My sorts work with small sets, but I haven't been able to test larger 2000 and above sets yet because of this. :(

I'll reply to myself. I ALSO tried:

Code:

 
do {
    cin >> number;
    list.push_back(number);
  } while (number);

and I STILL get CPU time limit exceeded :'(

Would you please post your data file?

The data file contains a series of random numbers using a different program that writes to a data.txt file.
I use srand(time(0)); cout << rand();

So the file looks like this:

1485738376
1444384990
1816004519
1128556181
1946001519
671306856
902458063
1329651005
371347021
2063196661
1678323328
1176164953

times a lot. Im trying to time quicksort by having it sort these files of 2000, 4000, 6000, etc elements.

I can't really reproduce your problem on my end. If the file name is somehow not named correctly (such as a missing extension) the redirection of cin will not be effective, though.

Well what would be causing me to get a bad_alloc error? And/or CPU time limit exceeded?

I add print statements after everything and the error seems to be only with adding ints to the vector with the while loop.
If i print out the capacity and size, it says zero for both, even after the push_back stuff.

I don't understand
