<> preface

Improve the shortcomings of the previous blog .

<> one , The number of surrounding mines is 0, Continuous automatic turning chess pieces

Mine sweeping doesn't have to click on a chess piece , If it is displayed as 0, It means that there is no thunder around , In this way, several pieces around will automatically turn over , If there is something around it, it shows as 0 of , There are automatic turns around , In turn ; Such a function I call “ Explosion screen ”, Sometimes it really blows up a lot , It will be better to clear the mine then ; Ray, let me go 10 individual , I wrote about the last blog , They are all very detailed ;

The code is as follows ：
void Findmines(char mine[Rows][Cols], char show[Rows][Cols], int x, int y) {
if (x == 0 || y == 0 || x == Rows - 1 || y == Cols - 1) { return ; } if
(show[x][y] != '*') return; if (show[x][y] == '*') { int ret = minenum(mine, x,
y); show[x][y] = ret + '0'; } if (show[x][y] == '0') { Findmines(mine, show, x
- 1, y - 1); Findmines(mine, show, x - 1, y); Findmines(mine, show, x - 1, y +
1); Findmines(mine, show, x, y - 1); Findmines(mine, show, x, y + 1);
Findmines(mine, show, x + 1, y - 1); Findmines(mine, show, x + 1, y);
Findmines(mine, show, x + 1, y + 1); }
<> two , Marking and unmarking

Marking and canceling functions are similar , When we can determine the location of the mine, we can mark the location of the mine , When we mark the wrong position, we can cancel the mark ; The code implementation is as follows ：
void concel(char show[Rows][Cols], int x, int y) { if (x == 0 || y == 0 || x
== Rows - 1 || y == Cols - 1) { printf(" Illegal coordinates , Please re-enter ：\n"); return; } if
(show[x][y] != '!') return; if (show[x][y] == '!') { show[x][y] = '*';
Initshow(show, Row, Col); } } void add(char show[Rows][Cols], int x, int y) {
if (x == 0 || y == 0 || x == Rows - 1 || y == Cols - 1) {
printf(" Illegal coordinates , Please re-enter ：\n"); return; } if (show[x][y] != '*') return; if
(show[x][y] == '*') { show[x][y] = '!'; Initshow(show, Row, Col);; } }
3. The total code is as follows

summary

Thank you for reading , I think this improved minesweeping code is much more optimized than the code in the previous issue , You can try the game experience by yourself , Personally, I think it's better ; Sanzi will be improved later , Gobang will also come true , However, there is no time to improve the code recently , All may be a little slow , It will take a little more time ;
