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 #include 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] <<" "; } cout << endl; } }
