C++ 写黑白棋，要求绘制6*6的棋盘，检测玩家的所有走法，人机对弈

下面是一个简单的C++黑白棋游戏代码示例，包括绘制棋盘、检测玩家走法和人机对弈。

#include <iostream>
#include <cstring>
using namespace std;

const int N = 6; // 棋盘大小
const char EMPTY = '-'; // 空格
const char BLACK = 'X'; // 黑色棋子
const char WHITE = 'O'; // 白色棋子

char board[N][N]; // 棋盘
bool turn = true; // true 表示黑棋，false 表示白棋

// 初始化棋盘
void init() {
    for (int i = 0; i < N; i++)
        for (int j = 0; j < N; j++)
            board[i][j] = EMPTY;
    board[N/2-1][N/2-1] = WHITE;
    board[N/2][N/2] = WHITE;
    board[N/2-1][N/2] = BLACK;
    board[N/2][N/2-1] = BLACK;
}

// 输出棋盘
void print_board() {
    cout << "  ";
    for (int i = 0; i < N; i++) cout << i+1 << " ";
    cout << endl;
    for (int i = 0; i < N; i++) {
        cout << i+1 << " ";
        for (int j = 0; j < N; j++)
            cout << board[i][j] << " ";
        cout << endl;
    }
}

// 判断是否能落子

该代码实现了基本的黑白棋游戏功能，包括绘制棋盘、检测玩家走法和人机对弈。玩家通过输入坐标来落子，AI通过搜索所有合法落子来选择最优的位置。
