示例1: check_win
//for checking if they won, we can simplify because if we check every turn
//then we *know* that a winning sequence must include that cell
bool check_win(board& b, unsigned x, char id, unsigned to_win) { //x == bin of last move
unsigned h = b.height();
unsigned w = b.num_bins();
unsigned y = 0;
for (; y < h; ++y) {
if (b[x][y] == 0) {
break;
}
}
--y;
//last move was at x,y
//check row
if (check_win(range<adapters::horiz_it>(b.at(0, y), b.at(w, y)), id, to_win)) {
return true;
}
//check column
if (check_win(range<adapters::vert_it>(b.at(x, 0), b.at(x, h)), id, to_win)) {
return true;
}
//check diagonals
int intercept;
int hs = h; //h signed
int ws = w; //w signed

unsigned xf;
unsigned yi;

//up slope:

//all of these magic numbers are based off geometry. I'm not going
//to prove it, as this is a program, not a proof, but if you want to
//see it, it's not hard. My copy is on a receipt somewhere in the
//trash :/

//down slope
//there are some unsigned -1s because i need an invalid index that is
//= to --0, so the underflow is OK. It will never be dereferenced.
