Thread: minesweeper...

how can I make a function to calculate number of mines near by?
I wrote as this.. but it does not work properly.

Code:

int calculate()
{
int sum = 0;
int i;
int j;

for(i=0; i<9; i++)
     for (j=0; j<9; j++)
      if (mines[i][j] != "*" )
      {
           if(mines[i+1][j] = "*");
           {
           sum = 1 + calculate ();
            }
                      else if(mines[i+1][j+1] = "*");
                        {
                        sum = 1 + calculate ();
                         }
                         else if(mines[i+1][j] = "*");
                                {
                            sum = 1 + calculate ();
                               }
            else if(mines[i+1][j-1] = "*");
                             {
                           sum = 1 + calculate ();
                         }
             else if(mines[i][j-1] = "*");
                       {
                          sum = 1 + calculate ();
                          }
                  else if(mines[i-1][j-1] = "*");
                           {
                           sum = 1 + calculate ();
                           }
                        else if(mines[i-1][j] = "*");
                                  {
                                    sum = 1 + calculate ();
                                       }
                               else(mines[i-1][j+1] = "*");
                                      {
                                           sum = 1 + calculate ();
                                          }

      return sum;
}
