I am making minesweeper for the standard console... So every space is represented by a unsigned char. The first four bits tell how many mines are touching the space. The 5th bit is set if it has been revealed. The 6th bit is set if it is a mine. So I have 2 "mine fields". The real one and the one the user sees. The real one just keeps track of what spaces the mines are on. The user one is the one that keeps track of how many mines each space is touching. To reveal the board, there's a function called burn. It calls itself recursively. It's supposed to only call itself if the space it's looking at isn't revealed, but it does so anyway. Or it could be that the revealed bit wasn't set, but unless I am COMPLETELY stoned, this should set the revealed bit:
That's excactly how I set itCode:#define REVEALED 16
user_field[number] |= REVEALED;
I don't know, I'm almost insane with frustration. I beg you to help me. Well, here's the code:
I realize all of the things I have missed, and I have noted them and will fix them as soon as I get this part to work. Thanks for your help.Code:#include <iostream>
