用c语言实现三子棋小游戏（人机对弈）
2. 题目分析- 创建并打印菜单
- 创建并初始化棋盘
- 打印棋盘
- 玩家下棋
- 电脑下棋
- 判断输赢，并展示结果
void menu()
{
printf(" ------------------------------n");
printf("| |n");
printf("| 1. game 0. exit |n");
printf("| |n");
printf(" ------------------------------n");
}
2) 初始化棋盘
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] = ' ';//可下棋位置初始化为空格
}
}
}
3) 打印棋盘
//打印棋盘
void DisplayBoard(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++)
{
printf(" %c ", board[i][j]);
//打印列分隔符
if (j < col-1)
{
printf("|");
}
}
printf("n");
//打印行分隔符
if (i < row-1)
{
printf("---|---|---n");
}
}
}
4) 玩家下棋
//玩家下棋 用“O”表示
void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0;//横坐标
int y = 0;//纵坐标
printf("玩家下棋：");
scanf("%d%d", &x, &y);
if (x > 0 && x <= row && y > 0 && y <= col)
{
if (board[x - 1][y - 1] == ' ')
{
board[x - 1][y - 1] = 'O';
}
else
{
printf("非法输入n");
PlayerMove(board, row, col);
}
}
else
{
printf("非法输入n");
PlayerMove(board, row, col);
}
}
5）电脑下棋
//电脑下棋 用“X”表示 版本1
void ComputerMove(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
while (1)
{
//IsFull函数在 6）判断胜负 中有说明
int flag = IsFull(board, row, col);//判断是否有位置可下 0--有
if (flag == 0)
{
//电脑下棋
int x = rand() % row;
int y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = 'X';
break;
}
}
}
}
6) 判断胜负
char IsWin(char board[ROW][COL], int row, int col)
{
//行
int i = 0;
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][0] == board[i][2]&&board[i][0]!=' ')
return board[i][0];
}
//列
int j = 0;
for (j = 0; j < col; j++)
{
if (board[0][j] == board[1][j] && board[0][j] == board[2][j]&&board[0][j]!=' ')
return board[0][j];
}
//对角线
if (board[0][0] == board[1][1] && board[2][2]==board[1][1] && 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];
//判断棋盘是否满
if (IsFull(board, row, col))
return 'y';//满了
return 'n';//未满，继续
}
4. 程序演示
1）菜单展示
2）打印棋盘
3）玩家获胜
4）电脑获胜
5）平局
