в C ++. В следующей программе я пишу я получаю эту ошибку:

g++ -o Blob blob.cc
blob.cc: In function 'int nonrecursivecountcells(color (*)[7], int, int)':
blob.cc:41: error: 'grid' was not declared in this scope

Вот код:

#include <iostream>
enum color {BACKGROUND, ABNORMAL, TEMPORARY};
const int ROW_SIZE = 7;
const int COL_SIZE = 7;
int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int, int);
using namespace std;


int main() 
{
  color grid[ROW_SIZE][COL_SIZE] =
    {{BACKGROUND, ABNORMAL, BACKGROUND, ABNORMAL, BACKGROUND, BACKGROUND, BACKGROUND},
      {ABNORMAL, ABNORMAL, BACKGROUND, ABNORMAL, BACKGROUND, BACKGROUND, BACKGROUND},
       {BACKGROUND, BACKGROUND, ABNORMAL, ABNORMAL, BACKGROUND, BACKGROUND, ABNORMAL},
        {BACKGROUND, BACKGROUND, BACKGROUND, ABNORMAL, ABNORMAL, ABNORMAL, BACKGROUND},
         {BACKGROUND, BACKGROUND, BACKGROUND, ABNORMAL, BACKGROUND, BACKGROUND, BACKGROUND},
          {BACKGROUND, BACKGROUND, BACKGROUND, BACKGROUND, BACKGROUND, ABNORMAL, BACKGROUND},
           {BACKGROUND, ABNORMAL, ABNORMAL, BACKGROUND, BACKGROUND, BACKGROUND, ABNORMAL}};

   cout << "Enter row number" << endl;
   int row;
   cin >> row;
   cout << "Enter column number" << endl;
   int column;
   cin >> column;

   int number = nonrecursivecountcells(grid, row, column);
   cout << "Number off cells in the blob that contains grid[" << row << "][" << column << "] are: " << number << endl;

   return 0;

}

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)
{
  if (row < 0 || row >= ROW_SIZE || column < 0 || column >= COL_SIZE)
  {
    return 0;
  }

  else if (grid[row][column] != ABNORMAL)
  {
    return 0;
  }

  else
  {
    grid[row][column] = TEMPORARY;
    return 1
    + nonrecursivecountcells(grid, row - 1, column - 1) + nonrecursivecountcells(grid, row - 1, column)
    + nonrecursivecountcells(grid, row - 1, column + 1) + nonrecursivecountcells(grid, row, column + 1)
    + nonrecursivecountcells(grid, row + 1, column + 1) + nonrecursivecountcells(grid, row + 1, column)
    + nonrecursivecountcells(grid, row + 1, column - 1) + nonrecursivecountcells(grid, row, column - 1);
  }
}

Может кто-нибудь помочь мне здесь? Благодарю.
