debug...

can't figure out what's wrong with this program...
it's minesweeper program..
input of (0, 0) is automatic win...
if I uncover some area that doesn't have mines, it opens all area.
can't figure out what's wrong..

PHP Code:

---

int calculate(int i, int j)
{

int sum = 0;


    /* Calculate values of cells surounding mines */
       if (mines[i][j] != '*')
      {
      if(mines[i+1][j] == '*')
           {
           sum = 1 + calculate(i, j);
            }
      else if(mines[i+1][j+1] == '*')
            {
               sum = 1 + calculate(i, j);
             }
           else if(mines[i+1][j] == '*')
                {
                    sum = 1 + calculate(i, j);
                 }
                 else if(mines[i+1][j-1] == '*')
                      {
                        sum = 1 + calculate(i, j);
                      }
                      else if(mines[i][j-1] == '*')
                           {
                           sum = 1 + calculate(i, j);
                            }
                           else if(mines[i-1][j-1] == '*')
                                {
                                sum = 1 + calculate(i, j);
                                }
                                else if(mines[i-1][j] == '*')
                                    {
                                    sum = 1 + calculate(i, j);
                                    }
                                    else
                                      {
                                         sum = 1 + calculate(i, j);
                                      }
           }

      return sum;
}

Please don't post hundreds of lines of code at a time. Attach a file if you insist on showing the entire program. This is one problem I spotted before I got tired of reading and quit:

Code:

---

for( x = 0; x < 9; x++ )

        for( y = 0; y < 9; y++ )

            mines[x][y] = '0';

---

You declare mines as a 10 x 10 array. Here however, you only initialize 9 x 9. This is not what you want. Try this:

for( x = 0; x < 10; x++ )

Remember, arrays go from 0 to size-1. Thus, valid array cells are 0 to 9. If you stop before 9, then your nineth column and nineth row never get filled.

Quzah.

i reduced the code above..
sorry about that..
i narrowed down to those two functions..

I found another problem: calculating portion does not work..
