C++ :: Reading Integers Out Of A Text File And Only Adds Positive Ones?

I'm basically trying to make a simple program that reads integers out of a text file and only adds the positive ones and not the negatives.

All is well except it won't take the last integer (the last line, I presume.) I took the negative out, nothing to do with that. I put more numbers in and I made the txt file less, no answer. No matter what the last number is, the program won't read it. I've been researching online and I've been seeing that it might be an issue with "while "!inFile.eof())".

Anyway here's the program:

#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile;
ofstream outFile;

[Code] .....

Here's the txt file:
5
6
-9
21
3

I'm always getting 32 for some reason.
