ifstream c++ problem

[chris200x9]

My ifstream is broken plain and simple. I've followed many tutorials, I've even posted here and everything looks right. I'm begging someone find what's wrong with this:

#include <iostream>
#include <fstream>
using namespace std;
int main(int argc, char** argv)
{
ifstream inData;
inData.open("out.txt");
int matrix2[9][9];
int counter = 0;
int i =0;
while(!inData.eof())
{
while (i < 9)
{
while (counter < 9)
{

inData >> matrix2[i][counter];
counter++;
}
counter = 0;
i++;
}
}
inData.close();
cout << matrix2[0][0];

return 0;
}


here is the contents of out:

0 3 0 9 0 2 0 4 0
6 0 0 0 0 0 0 0 5
0 0 0 0 1 0 0 0 0
8 0 0 2 0 3 0 0 7
0 0 4 0 5 0 6 0 0
9 0 0 7 0 8 0 0 2
0 0 0 0 9 0 0 0 0
7 0 0 0 0 0 0 0 1
0 5 0 6 0 4 0 9 0
When I run the program nothing happens, I have to hit control c.

I have found a workaround of just reading the file into an array, but I still don't know exactly why the above does not work.

I believe you need to reset i


#include <iostream>
#include <fstream>

using namespace std;

int main(int argc, char** argv)
{
ifstream inData;
inData.open("out.txt");
int matrix2[9][9];
int counter = 0;
int i =0;

while(!inData.eof()) {
while (i < 9) {
while ((!inData.eof())&&(counter < 9)) {
inData >> matrix2[i][counter];
counter++;
}
counter = 0;
i++;
}
i = 0;
}

inData.close();
cout << matrix2[0][0];

return 0;
}

ah thanks!
