这篇“C语言怎么通过递归实现扫雷游戏”文章的知识点大部分人都不太理解,所以小编给大家总结了以下内容,内容详细,步骤清晰,具有一定的借鉴价值,希望大家阅读完这篇文章能有所收获,下面我们一起来看看这篇“C语言怎么通过递归实现扫雷游戏”文章吧。
用户选择菜单
void menu(){printf("****************************\n");printf("******** 1.play **********\n");printf("******** 0.exit **********\n");printf("****************************\n");}
用户按1进入游戏
棋盘初始化
void Itnboard(char board[ROWS][COLS], int rows, int cols,char c){int i, j;for (i = 0; i < rows; i++){for (j = 0; j <cols; j++){board[i][j] = c;}}}
创建数组,并对其进行初始化
布置雷(随机布置)
void Setboard(char board[ROWS][COLS], int row, int col){int count = Easy_count;while (count){int x = rand() % row+1;int y = rand() % col+1;if (board[x][y] == '0'){board[x][y] = '1';count--;}}}
用time函数产生随机值
打印棋盘
void Displayboard(char board[ROWS][COLS], int row, int col){int i, j;for (i = 0; i <= col; i++){printf("%d ", i);}printf("\n");for (i = 1; i <= row; i++){printf("%d ", i);for (j = 1; j <= col; j++){printf("%c ", board[i][j]);}printf("\n");}}
打印棋盘
玩家下棋
void Player(char board[ROWS][COLS], char show[ROWS][COLS], int row, int col){int x, y;int count = 0;while (1){printf("请排雷:\n");scanf("%d %d", &x, &y);if (x >= 1 && x <= 9 && y >= 1 && y <= 9){if (board[x][y] == '0'){Openboard(show, board, x, y);Displayboard(show, ROW, COL);}else if (board[x][y] == '1'){printf("你死了\n");break;}}else{printf("请重新输入");}int i, j;for (i = 1; i <= row; i++){for (j = 1; j <= col; j++){if (show[i][j] == '*'){count++;}}}if (count == Easy_count){printf("成功\n"); //这里的判断条件是遍历整个数组,统计雷的个数,如果雷的个数等于所剩余未排的*,说明排雷成功break;}}}
用户输入值,并进行判断,如果该位置没有雷,我们进入展开函数
棋盘展开
void Openboard(char show[ROWS][COLS], char board[ROWS][COLS], int row, int col){if (row >= 1 && row <= ROW && col >= 1 && col <= COL){int count=sum(board, row, col);if (count != 0){show[row][col] = count + '0';}else if (show[row][col] != '_'){show[row][col] = '_';int i = 0, j = 0;for (i = row - 1; i <= row + 1; i++){for (j = col - 1; j <= col + 1; j++){Openboard(show, board, i,j);}}}else{return;}}}
如果用户输入的这个位置没有雷,我们对其周围8个位置进行判断是否有雷,若有雷,我们把雷的个数显示在该位置上,若其周围8个位置没有雷并且不是下划线,我们把这个位置赋值为下划线,然后并对其8个位置进行同样的判断,如果周围没雷,而且周围的棋子也不是下划线,我们对其进行返回。
展开部分思维导图
展开函数最后一个else return 作用
这里我们show棋盘有三种情况,
该位置是*
该位置是下划线
该位置是雷的个数
else
return;
这里是作用:如果是下划线,我们就返回上一层函数。因为如果这里不是下划线,我们会在else return 之前的语句中进行判断,并对其周围8个位置进行操作,然后再对这8个棋子各个周围8个位置进行判断并操作,如果这里是下划线,就说明由这个位置为中心的周围8个棋子已经判断过了,并且以这8个位置为中心,已经递归过了,我们不需要再进行判断,所以直接返回就行
周围雷个数判断
int sum(char board[ROWS][COLS], int x, int y){return (board[x - 1][y - 1] +board[x - 1][y] +board[x - 1][y + 1] +board[x][y - 1] +board[x][y + 1] +board[x + 1][y - 1] +board[x + 1][y] +board[x + 1][y + 1] - 8 * '0');}
