Beginner Problem with Loop

I wrote a program for an assignment that should read data from a file on the computer then display the sum of both the positive integers and negative integers. However, when I run my program it goes into an infinite loop. I need to understand what I am doing wrong. Any help would be greatly appreciated.

Code:

---

#include <iostream>
#include <fstream>
using namespace std;

int main()
{
    ifstream inputFile;
    int even = 0;
    int odd = 0;
    int x;

    inputFile.open("C:....\hw4dataf11.txt"); //I have attached the file to this post

    if (!inputFile)
        cout << "Error opening file.\n";

    while(!inputFile.eof()){

        if(x % 2 == 0){
            even += x;
            cout << "Number of even numbers is: " << even << endl;
            even++;
        }

        else {
            odd += x;
            cout << "Number of odd numbers is: " << odd << endl;
            odd++;
        }
    }


    inputFile.close();
    cout << "Program is finished. \n";Attachment 10981

    return 0;
}

Where is the variable x coming from? You open the file and you go into a loop, but you don't actually read in x. Put a priming read (read in x) before the while loop and then read in another x at the end of the while loop.

This is a common problem, discussed in the FAQ on this site.

Hmm, that article is more about C though. Here's a discussion of the same problem in C++.

Thank you both very much. I appreciate the help. ^_^

Yes, that link did the trick!! Also, Linell, thank you for reminding me about the priming reads. You two really helped me out. ^_^
