:sunny::sunny::sunny: 今天学习一个自制实现三子棋小游戏

一、效果展示

:sunny::sunny::sunny: 我们可以用纯C实现三子棋小游戏，与电脑进行对弈，效果如下：

二、游戏功能实现（详细版）

1.棋盘初始化

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.打印棋盘

void DispalyBoard(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 < col; j++) {
                    printf("---");
                    if (j < col - 1) 
                        printf("|");
                }
                    printf("\n");
               
            }
        }
    }

3.玩家下棋

void PlayerMove(char board[ROW][COL], int row, int col) {
    int x = 0;
    int y = 0;
    printf("玩家请下棋：>\n");
    while (1) {
        printf("请输入坐标：>");
        scanf("%d %d", &x, &y);
        //对坐标进行判断
        if (x >= 1 && x <= row && y >= 1 && y <= col) {
            if (board[x - 1][y - 1] = ' ') {
                board[x - 1][y - 1] = '*';
                break;

            }
            else
            {
                printf("此坐标已下，请选择其他位置\n");
            }
        }
        else {
            printf("坐标超出范围，请选择其他位置\n");
        }
    }
   }

4.电脑下棋

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

:dolphin::dolphin::dolphin:此处电脑下棋是无脑的，不含任何技术的，大家感兴趣的话，可以让电脑成为不败战胜

5.判断游戏输赢

char IsWin(char board[ROW][COL], int row, int col)
{
    //判断每一行是否相等
    int i = 0;
    for (i = 0; i < row; i++)
    {
        if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
        {
            return board[i][1];//
        }
    }

    //判断每一列是否相等
    int j = 0;
    for (j = 0; j < col; j++)
    {
        if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] != ' ')
        {
            return board[1][j];
        }
    }
    //判断对角线是否相等
    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];
    }

    //没有人赢，就要平局
    if (IsFull(board, row, col))
    {
        return 'Q';
    }

    //游戏继续
    return 'C';
}

6.判断游戏是否平局

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;
}

            //判断输赢
