【c语言】扫雷游戏实现
设计思路
- 由于这个代码相较于平常所写的，代码比较多，故我采用多文件管理，减少维护成本
- 函数声明放在game.h头文件
- 与游戏有关函数定义放在game.c源文件
- main函数单独放在main.c中
- 设计代码时，先写出主体逻辑，然后边测试逻辑的正确性边进行代码的具体实现
如下：
主函数
int main(void)
{
int input = 0;
do
{
menu();
printf("请输入你的选择:");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏！\n");
break;
default:
printf("输入错误，请重新输入！\n");
break;
}
} while (input);
return 0;
}
菜单
void menu()
{
printf("****************************************\n");
printf("******* 1.play 0.exit *********\n");
printf("****************************************\n");
}
game函数的逻辑
- 设计时需要一个棋盘布置雷，我们把雷设置为字符1(后续好计算雷的个数)，其他设置为字符0，此时若要显示你所输入的坐标周围雷的个数，若有一个雷，就会与雷冲突，所以我们设置两个数组一个布置雷，一个显示周围雷的数量
- 由于后面要检查周围8个位置的雷个数，在边界时防止数组越界，故数组扩大一圈
- 初识化棋盘，将初始化的字符作为参数传递
- 设置雷
- 打印显示雷数量的棋盘
- 开始排雷
void game()
{
char mine[ROWS][COLS] = { 0 };
char show[ROWS][COLS] = { 0 };
srand((unsigned)time(NULL));
InitBoard(mine, ROWS, COLS, '0');
InitBoard(show, ROWS, COLS, '*');
SetMine(mine, ROW, COL, DIGIT_MINE);
PrintBoard(show, ROW, COL);
CheckMine(mine, show, ROW, COL, DIGIT_MINE);
}
初始化棋盘
void InitBoard(char board[ROWS][COLS], int rows, int cols, char set)
{
int i = 0;
int j = 0;
for (i = 0; i < rows; i++)
{
for (j = 0; j < cols; j++)
{
board[i][j] = set;
}
}
}
布置雷
void SetMine(char mine[ROWS][COLS], int row, int col, int digitMine)
{
int x = 0;
int y = 0;
while (digitMine > 0)
{
x = rand() % row + 1;
y = rand() % col + 1;
if (mine[x][y] == '0')
{
mine[x][y] = '1';
digitMine--;
}
}
}
打印棋盘
void PrintBoard(char board[ROWS][COLS], int row, int col)
{
int i = 0;
int j = 0;
for (j = 0; j <= col; j++)
{
printf("%d ", j);
}
printf("\n");
for (i = 1; i <= row; i++)
{
printf("%d ", i);
for (j = 1; j <= col; j++)
{
printf("%c ", board[i][j]);
}
printf("\n");
}
}
排查雷
void CheckMine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col, int digitMine)
{
int x = 0;
int y = 0;
int ret = 0;
int count = 0;
while (row * col - digitMine > count)
{
printf("请输入坐标：");
scanf("%d %d", &x, &y);
if (mine[x][y] == '1')
{
printf("你已被炸死！\n");
PrintBoard(mine, ROW, COL);
break;
}
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (show[x][y] == '*')
{
ret = GetMine(mine, x, y);
show[x][y] = ret + '0';
count++;
PrintBoard(show, ROW, COL);
}
else
{
printf("该坐标已被排查！\n");
}
}
else
{
printf("输入错误，请重新输入！\n");
}
}
if (count == row * col - digitMine)
{
printf("恭喜你排雷成功！\n");
PrintBoard(mine, ROW, COL);
}
}
坐标周围雷的数量
由于雷是用字符1表示，故把周围的字符都相加减去8个字符0，就会得到周围雷的个数
int GetMine(char mine[ROWS][COLS], int x, int y)
{
return mine[x - 1][y] + \
mine[x + 1][y] + \
mine[x][y - 1] + \
mine[x][y + 1] + \
mine[x - 1][y - 1] + \
mine[x + 1][y + 1] + \
mine[x - 1][y + 1] + \
mine[x + 1][y - 1] - 8 * '0';
}

#define ROWS ROW+2

mine[x + 1][y] + \

mine[x + 1][y - 1] - 8 * '0';
