my c++ code isn't working, i want to transfer numbers 1-9 in my file to an 2D array but the array only gets 9 being put into it. the file is also returning an extra 9. Below is the code:

#include <iostream>
#include <fstream>

using namespace std;
int main() {
int numbers;
const int rows = 3;
const int columns = 3;
int array [rows] [columns];

ofstream write;
write.open("file.txt");
write << 1 << endl << 2 << endl << 3 << endl << 4 << endl << 5 << endl << 6 << endl << 7 << endl << 8 << endl << 9 << endl;
write.close();

ifstream read ("file.txt");
while (!read.eof())
{
if (read.eof())
break;
read >> numbers;
cout << numbers << endl;
for (int r = 0; r < rows; r++)
{
for (int c = 0; c < columns; c++)
{
array [r] [c] = numbers;
}
}
}

for (int r = 0; r < rows; r++)
{
for (int c = 0; c < columns; c++)
{
cout << array [r] [c] <<" ";
