1. ## 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; }  ```

2. 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.

3. i reduced the code above..
