用c++写一个五子棋游戏 包含人人对战与人机对战

好的，下面是一个基本的五子棋游戏的 C++ 代码，包含人人对战和人机对战。请注意，这只是一个基本的示例代码，您可以根据需要进行修改和优化。

#include <iostream>
#include <vector>
#include <ctime>
#include <cstdlib>
using namespace std;

const int BOARD_SIZE = 15;  // 棋盘大小
const int EMPTY = 0;       // 空棋子
const int BLACK = 1;       // 黑棋
const int WHITE = -1;      // 白棋

// 棋盘类
class Board {
public:
    Board() {
        for(int i = 0; i < BOARD_SIZE; i++) {
            vector<int> row(BOARD_SIZE, EMPTY);
            board.push_back(row);
        }
    }

    // 判断当前位置是否越界
    bool is_valid(int x, int y) const {
        return x >= 0 && x < BOARD_SIZE && y >= 0 && y < BOARD_SIZE;
    }

    // 判断当前位置是否为空
    bool is_empty(int x, int y) const {
        return board[x][y] == EMPTY;
    }

    // 在当前位置落子
    void move(int x, int y, int player) {
        board[x][y] = player;
    }

    // 检查是否有五子连珠
    bool check_win(int x, int y) const {
        int player = board[x][y];
