Average a bunch of lines (C++)

A Short C++ program to average a bunch of entries on a bunch of lines. I.e.:




1 2 3 4 5 6 END OF LINE

7 8 9 10 11 12 END OF LINE

13 14 15 16 17 18 END OF LINE



Would average 1 7 13. 2 8 and 14 etc...

#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>

using namespace std;

int main(int argc,char **argv) {

  ifstream infile(argv[1]);

  int count=0;
  vector<double> sums(1000,0);
  for(;!infile.eof();) {
    string instring;
    getline(infile,instring);

    stringstream ss(instring);

    for(int n=0;!ss.eof();n++) {
      double cur;
      ss >> cur;
      sums[n]+= cur;
    }
    count++;
  }

  for(vector<double>::iterator i = sums.begin();i != sums.end();i++) {
    cout << (*i)/count << " ";
  }
  cout << endl;

}
