c语言代码实现三子棋（详解）
设计总体思路
实现游戏可以一直玩，先打印棋盘，玩家和电脑下棋，最后分出胜负。
具体步骤
目录
一、打印游戏菜单界面
二、打印棋盘
三、玩家下棋
四、电脑下棋
五、判断输赢
一、打印游戏菜单界面
首先界面有选项选择，开始你的游戏，代码以及效果图如下：
void menu()//打印菜单
{
printf("******************\n");
printf("******1.play******\n");
printf("******0.exit******\n");
printf("******************\n");
}
int main()
{
int input = 0;
srand((unsigned int)time(NULL));//电脑随机产生数字
do
{
menu();
printf("请选择->\n");
scanf("%d", &input);
switch (input)//选择选项
{
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");
}
} while (input);
return 0;
}
二、打印棋盘
创建并初始化数组，再打印棋盘，代码以及效果图如下：
//存放下棋数据
char board[ROW][COL] = { 0 };
//初始化棋盘为全空格
InitBoard(board, ROW, COL);
//初始化棋盘为空格
void InitBoard(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++)
{
board[i][j] = ' ';
}
}
}
//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col)//打印棋盘
{
//打印数据
int i = 0;
for (i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col; j++)
{
printf(" %c ",board[i][j]);//别忘记board[i][j]
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
//打印分割行
if (i < row-1)//记住 row-1
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
}
}
}
三、玩家下棋
'*' 代表玩家下的棋子。
代码思路，第一步创建玩家下棋的函数player_move（）并输入坐标，代码图如下：
//玩家下棋
void player_move(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);
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
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("非法坐标，请重新输入\n");
}
}
}四、电脑下棋
'#' 代表电脑下的棋子。
代码思路，第一步创建电脑下棋的函数computer_move（）并输入坐标，代码图如下：
void computer_move(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑下棋：>\n");
while (1)
{
x = rand() % 3;
y = rand() % 3;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}五、判断输赢
创建判断输赢的is_win()函数，while()循环实现玩家和电脑可以轮流下直到一方胜利，
如果有三个 '*' 符号连成一条线，代表玩家获胜，如果有三个 '#' 符号连成一条线，代表电脑获胜，或者平局。is_win（）函数中玩家赢返回'*'，电脑赢返回-'#'，平局返回'Q'，继续返回'C',
while (1)//玩家和电脑轮流下棋，直到一方胜利
{ //玩家下棋
player_move(board, ROW, COL);
//打印棋盘
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
if (ret != 'C')
{
break;
}
//电脑下棋
computer_move(board, ROW, COL);
//打印棋盘
DisplayBoard(board, ROW, COL);
ret = is_win(board, ROW, COL);
if (ret != 'C')
{
break;
}
}
if (ret == '*')
{
printf("玩家获胜\n");
}
else if (ret == '#')
{
printf("电脑获胜\n");
}
else // (ret == 'Q')
{
printf("平局\n");
}
DisplayBoard(board, ROW, COL);
}
//判断输赢
char is_win(char board[ROW][COL], int row, int col)
{
//判断每一行是否都相等
int i = 0;
for (i = 0; i < col; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
{
return board[i][1];
}
}
//判断每一列是否都相等
for (i = 0; i < col; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != ' ')
{
return board[i][1];
}
}
//判断对角线是否都相等
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 (is_full(board, row, col) == 1)
{
return 'Q';
}
//继续
return 'C';
}
