getting odd errors when i try to read data into a 2d array

[toshbar]

I'm getting a few errors when I try to compile my code and I have no idea how to fix them

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

#include "input.dat"

class sudoku{
 private:
  const int row;
  const int col;
  int game[][9];

 public:
  void readNumbersIn();
};//end class

void sudoku::readNumbersIn()
{

  int game[row][col];
  ifstream fin;
  fin.open("input.dat");

  for(int i=0; i<row; i++)
    {
      for(int j=0; j<col; j++)
        {
         fin >> game[row][col];
        }
    }

  for(int i=0; i<row; i++)
    {
      for(int j=0; j<col; j++)
        {
          cout << game[row][col]  << "  ";
        }
      cout << endl;
    }

}//end void readNumbersIn

the input.dat file contains

4 3 5 2 6 9 7 8 1
6 8 2 5 7 1 4 9 3
1 9 7 8 3 4 5 6 2
8 2 6 1 9 5 3 4 7
3 7 4 6 8 2 9 1 5
9 5 1 7 4 3 6 2 8
5 1 9 3 2 6 8 7 4
2 4 8 9 5 7 1 3 6
7 6 3 4 1 8 2 5 9

the errors are:

input.dat:1: error: expected unqualified-id before numeric constant
homework13.h:18: error: âsudokuâ has not been declared
homework13.h: In function âvoid readNumbersIn()â:
homework13.h:21: error: ârowâ was not declared in this scope
homework13.h:21: error: âcolâ was not declared in this scope
homework13.h:29: error: âgameâ was not declared in this scope
homework13.h:37: error: âgameâ was not declared in this scope



1) why are my delcarations not being passed from my class?
2) i dont understand the error in my input.dat file

You write:

using namespace std;

#include "input.dat"

class sudoku{

The compiler sees:

using namespace std;

4 3 5 2 6 9 7 8 1
6 8 2 5 7 1 4 9 3
1 9 7 8 3 4 5 6 2
8 2 6 1 9 5 3 4 7
3 7 4 6 8 2 9 1 5
9 5 1 7 4 3 6 2 8
5 1 9 3 2 6 8 7 4
2 4 8 9 5 7 1 3 6
7 6 3 4 1 8 2 5 9

class sudoku{

You must do something different.
