Answer 1

Cheers for the ideas guys, i was trying to do something like this:
          for(int i=0; i<6; i++)
               for(int j=0; j<7; j++)
                    if(win[i][j] != 0 &&
                       win[i][j]== win[i+1][j] &&
                       win[i][j]== win[i+2][j] &&
                       win[i][j]== win[i+3][j])
                                                                       //I would have a bit of code here that changed the value of a boolean variable
          }but it wont compile, any way of doing something along thesed lines?
