    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 iint j)
    {

    int sum 0;


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

          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.

    Hope is the first step on the road to disappointment.
