# 1.游戏

game.h 用来放函数的声明

game.c 用来放函数的定义

test.c 游戏的主体文件

``````void game()
{
char board[ROW][COL];
InitBoard(board, ROW, COL);
//打印棋盘
DisPlayBoard(board, ROW, COL);
//下棋

char ret = 0;
while(1)
{
//玩家下棋
PlayerMove(board, ROW, COL);
//打印棋盘
DisPlayBoard(board, ROW, COL);

if (ret != 'C')
{

}

//电脑下棋

if (ret != 'C')
{
break;
}

}
if (ret == '*')
{
printf("玩家赢n");
}
else if (ret == '#')
{
printf("电脑赢n");
}
else
{
printf("平局n");
}
}``````

下面开始我们的学习吧：

# 2.函数部分

``````//菜单
//游戏
void game();
//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//打印棋盘
void DisPlayBoard(char board[ROW][COL], int row, int col);
//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col);
//电脑下棋
void ComputeMove(char board[ROW][COL], int row, int col);
//判断输赢
char IsWin(char board[ROW][COL], int row, int col);
//判断棋盘是否满了
int IsFull(char board[ROW][COL], int row, int col);
``````

## 2.1.菜单

``````void menu()
{
printf("*********************n");
printf("******  1.play ******n");
printf("******  0.exit ******n");
printf("*********************n");
}
``````

## 2.2.初始化棋盘

``````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] = ' ';
}
}
}``````

## 2.3.打印棋盘

在一个3*3的棋盘中，我们不仅要打印棋盘的数线，也要打印棋盘的横线，还要考虑棋子位置等问题。

``````void DisPlayBoard(char board[ROW][COL], int row, int col)
{
int i = 0, j = 0;
for (i = 0; i < row; i++)
{
//打印数据
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("n");

//打印分割线
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
printf("n");
}
}
}``````

## 2.4.玩家下棋

``````void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0, y = 0;
printf("玩家下棋：->n");

while(1)
{
printf("请输入下棋坐标，中间使用空格->");
scanf("%d %d", &x, &y);
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (board[x - 1][y - 1] == ' ')//可以落子
{
board[x - 1][y - 1] = '*';
break;
}
else//不能落子
{
printf("坐标被占用，不能落子，重新输入>n");
}
}
else
{
printf("坐标非法，重新输入n");
}
}
}``````

## 2.5.电脑下棋

``````void ComputeMove(char board[ROW][COL], int row, int col)
{
int x = 0, y = 0;
printf("电脑下棋：>n");

while(1)
{
x = rand() % row;
y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}``````

## 2.6.判断输赢

``````char IsWin(char board[ROW][COL], int row, int col)
{
//赢
//行
int i = 0;
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ')
{
return board[i][1];
}
}
//列
for (i = 0; i < col; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ')
{
return board[0][i];
}
}
//斜线
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[0][0] != ' ')
{
return board[0][0];
}
if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[0][2] != ' ')
{
return board[0][2];
}
//平局
if (IsFull(board, ROW, COL)==1)
{
return 'Q';
}
//继续
return 'C';
}
``````

## 2.7.判断棋盘是否已满

``````int IsFull(char board[ROW][COL], int row, int col)
{
int i = 0, j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
if (board[i][j] == ' ')
return 0;
}
}
return 1;
}``````

哈哈，是电脑赢得了本次游戏，如果感到不过瘾的话可以再来一把，哈哈哈
