一 游戏逻辑
1.菜单界面选择开始或者退出游戏
2.创建棋盘并初始化
3.打印棋盘
4.玩家与电脑交替下棋
5.判断输赢
二 模块化
1.游戏菜单
void menu()
{
printf("******************************\n");
printf("********* 1.play *********\n");
printf("********* 0.exit ********\n");
printf("******************************\n");
}2.创建棋盘并初始化
char board[ROW][COL] = { 0 };
void InitBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
board[i][j] = ' ';
}
}
}3.打印棋盘
版本1:
只能打印3x3棋盘
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
//数据
printf(" %c | %c | %c \n", board[i][0], board[i][0], board[i][1]);
//分隔行
if(i < row - 1)
printf("---|---|---\n");
}
}
版本2:
配合宏定义可以灵活修改
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
//数据 把 %c |看成一组数据,但最后一个|不打印
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if(j < col -1)//最后一个|不用打印
printf("|");
}
printf("\n"); //打印完一行换行
//分隔行 把---|看成一组数据 最后一个|不打印
if (i < row - 1)//最后一行分隔行也无需打印
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
}
printf("\n"); //打印完一行换行
}
}4.玩家与电脑交替下棋
void player_move(char board[ROW][COL], int row, int col)
{
printf("玩家下棋:>");
int x = 0;
int y = 0;
while (1)
{
scanf("%d %d", &x, &y);
if (x >= 1 && x <= row && y >= 1 && y <= col)//坐标合法性判断
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else
{
printf("该坐标被占用,请重新输入\n");
}
}
else
{
printf("坐标非法,请重新输入\n");
}
}
}
void computer_move(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑下棋:>\n");
x = rand() % ROW;//0 - 2
y = rand() % COL;//0 - 2
while (1)
{
x = rand() % ROW;//0 - 2
y = rand() % COL;//0 - 2
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}5.判断输赢
版本1:
is_win被写死了,只能判断ROW COL为3的情况
char is_win(char board[ROW][COL], int row, int col)
{
int i = 0;
//三行判断
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
{
return board[i][1];
}
}
//三列判断
for (i = 0; i < col; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
{
return board[1][i];
}
}
//判断对角线
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
{
return board[1][1];
}
if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
{
return board[1][1];
}
//判断平局
if (1 == is_full(board, row, col))
{
return 'Q';
}
//游戏继续

}版本2:
is_win可以适应nxn棋盘

修改ROW,COL可以实现五子棋
#define ROW 5
#define COL 5
?五 细节
1.
棋盘数据打印是把???%c? |看成一组数据但最后一个|不打印
分隔行 把---|看成一组数据但最后一个|不打印且最后一行分隔行也无需打印
2.
把要用到的头文件及函数都在头文件中声明,这样在.c文件中就只需引用自己创建的头文件,避免了头文件的重复定义
3.
用时间戳生成随机数的时候，先使用srand函数设置种子,注意srand函数不要放在实现函数的内部，不然会导致随机数生成的很近,srand函数每次游戏只需重新设置一次
?
参考MSDN关于rand的说明
The rand function returns a pseudorandom integer in the range 0 to RAND_MAX.
Use the srand function to seed the pseudorandom-number generator before calling rand.
