C语言实现三子棋游戏

打印菜单

void meau()
{
    printf("************************\n");
    printf("******1.开始游戏********\n");
    printf("******0.退出游戏********\n");
    printf("************************\n");
}

打印棋盘：

void PrintBoard(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 (j < col - 1)
                printf(" %c|", board[i][j]);
            else
                printf("%c", board[i][j]);
        }
        printf("\n");
        if (i < row-1)
        {
            printf("--|--|--\n");
        }
    }
}

玩家走：

void PlayerMove(char board[ROW][COL], int row, int col)

{
    int a = 0;
    int b = 0;

    printf("玩家走\n");
        while (1)
        {
            scanf("%d%d", &a, &b);
            if (board[a - 1][b - 1] == ' '&&a>0&&a<4&&b>0&&b<4)
            {
                board[a - 1][b - 1] = 'X';
                PrintBoard(board, ROW, COL);
                break;
            }
            else
                printf("输入坐标有误\n");
        }
}

电脑走：

void CompuertMove(char board[ROW][COL], int row, int col)
{
    int a = 0;
    int b = 0;
    srand((unsigned)time(NULL));
    printf("电脑走\n");
    while (1)
    {
        a = rand() % 3;
        b = rand() % 3;
        if (board[a][b] == ' ')
        {
            board[a][b] = 'O';
            PrintBoard(board, row, col);
            break;
        }
    }   
}

输赢判断：

char IsWin(char board[ROW][COL], int row, int col)

{
    int i = 0;
    int j = 0;
    int count = 0;
    for (i = 0; i < row; i++)
    {
        if (board[i][0] == board[i][1] && board[i][1] == board[i][2])
            return board[i][1];
    }
    for (j = 0; j < col; j++)
    {
        if (board[0][j] == board[1][j] && board[1][j] == board[2][j])
            return board[1][j];
    }

    if (board[0][0] == board[1][1] && board[1][1]==board[2][2])
    {
        return board[1][1];
    }
    if (board[0][2] == board[1][1] && board[1][1] == board[2][0])
    {
        return board[1][1];
    }
    for (i = 0; i < row; i++)
    {
        for (j = 0; j < col; j++)
        {
            if (board[i][j] != ' ')
                count++;
        }
    }
    if (count == 9)
    {
        return 'P';
    }

    return '1';
}

game函数调用：

void game()
{
    int i = 0;
    int j = 0;
    char ret = 0;
    char board[ROW][COL] = { 0 };
    for (i = 0; i < ROW; i++)
    {
        for (j = 0; j < COL; j++)
        {
            board[i][j] = ' ';
        }
    }
    //打印棋盘
    PrintBoard(board, ROW, COL);
    //比拼
    while (1)
    {
        PlayerMove(board, ROW, COL);
        ret = IsWin(board, ROW, COL);
        if (ret == 'X')
        {
            printf("玩家赢！\n");
            break;
        }
        else if (ret == 'O')
        {
            printf("电脑赢\n");
            break;
        }
        else if (ret == 'P')
        {
            printf("平局\n");
            break;
        }
        CompuertMove(board, ROW, COL);
        ret = IsWin(board, ROW, COL);

        if (ret == 'X')
        {
            printf("玩家赢！\n");
            break;
        }
        else if (ret == 'O')
        {
            printf("电脑赢\n");
            break;
        }
        else if (ret == 'P')
        {
            printf("平局\n");
            break;
        }
    }
}

当 输赢判断 函数返回值为‘X’时 ，结果为玩家赢，返回值为‘O’时，结果为电脑赢，返回值为‘P’时，结果为平局。

主函数调用：

int main()
{
    int n = 1;
    while (n)
    {
        n = 0;
        meau();
        printf("请选择-> \n");
        scanf("%d", &n);
        switch (n)
        {
        case 0:
            printf("退出成功\n");
            break;
        case 1:
            game();

            break;
        default:
            printf("输入错误 请重新输入:\n");
            break;
        }
    }
    system("pause");
    return 0;
}

通过玩家选择 开始或退出游戏

玩家通过选择坐标进行游戏
