五子棋首先要有几个关键的功能:
1. 构建棋盘
2. 玩家下棋
3. 电脑下棋
4. 判断输赢
通过观察棋盘发现棋盘是由分割符以及空格实现,实际上棋盘的空格就是之后要下棋的位置,空格代表这个位置的初始化,即让每一个char类型元素初始化为空格,再通过一些处理显示棋盘。
代码如下(示例):
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] = ' ';
}
}
}
void DispalyBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
//打印数据
//printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);
int j = 0;
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
//打印分割信息
//printf("---|---|---\n");
if (i < row - 1)
{
int j = 0;
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
printf("\n");
}
}
}
首先我们通过坐标的输入实现了定位下棋的位置,而电脑下棋我们利用随机数rand(),以及srand()进行操作,而随机数的根本来源于时间戳的变化
代码如下(示例):
void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("玩家下棋:>\n");
while (1)
{
printf("请输入坐标:>");
scanf("%d %d", &x, &y);
//坐标范围合法的判断
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else
{
printf("坐标被占用,不能下棋,请选择其他位置\n");
}
}
else
{
printf("坐标非法,请重新输入\n");
}
}
}
void ComputerMove(char board[ROW][COL], int row, int col)
{
printf("电脑下棋:>\n");
int x = 0;
int y = 0;
while (1)
{
x = rand() % row;//0~2
y = rand() % col;//0~2
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
如何进行判断输赢呢?
有以下几种情况:
1.*符号满足,玩家赢了
2.#符号满足,电脑赢了
3.棋盘位置占满,并且都没满足,平局
4.棋盘位置未满,并且都没满足,继续下棋
//满了就返回1
//不满 返回0
int IsFull(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++)
{
if (board[i][j] == ' ')
{
return 0;
}
}
}
return 1;
}
char IsWin(char board[ROW][COL], int row, int col)
{
//行
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
int nums = 0;
for (j = 0; j < col - 1; j++)
{
if (board[i][j] == board[i][j + 1]&&board[i][j] != ' ')
nums++;
}
if (nums == col - 1)
return board[i][j];
}
//列
for (i = 0; i < col; i++)
{
int nums = 0;
for (j = 0; j < row - 1; j++)
{
if (board[j][i] == board[j + 1][i] && board[i][j] != ' ')
{
nums++;
}
}
if (nums == row - 1)
{
return board[j][i];
}
}
//前提是棋盘为正方形
//对角线
int nums = 0;
for (i=0,j=0;i<row-1,j<col-1;i++,j++)
{
if (board[i][j] == board[i + 1][j + 1] && board[i][j] != ' ')
{
nums++;
}
}
if (nums == row - 1)
return board[i-1][j-1];
nums = 0;//注意
for (i = 0, j = col-1; i < row - 1, j >0; i++, j--)
{
if (board[i][j] == board[i + 1][j - 1] && board[i][j] != ' ')
{
nums++;
}
}
if (nums == row - 1)
return board[i-1][j+1];
//没有人赢,就要平局
if (IsFull(board, row, col))
{
return 'Q';
}
//游戏继续
return 'C';
}
这里显示的结果跟初始化的结果相比,空格的位置会被棋子覆盖
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
if (i < row - 1)
{
int j = 0;
for (j = 0; j < row; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
printf("\n");
}
}
}

通过以上的代码,是对数组以及函数的一种锻炼,是新手非常适合做的小程序,除了处理这些逻辑关系之外,更要清楚随机数如何运用以及其与时间戳之间的配合关系,以上总结,希望小伙伴们能够理解的更加深刻。码字不易,多多支持!
