C++代码实现 五子棋

下面是一个简单的C++代码实现五子棋的示例：

#include <iostream>
#include <vector>

using namespace std;

const int SIZE = 15;

enum class ChessPiece { None, Black, White };

class GobangGame {
public:
    GobangGame() {
        board.resize(SIZE, vector<ChessPiece>(SIZE, ChessPiece::None));
        currentPlayer = ChessPiece::Black;
    }

    void play() {
        while (true) {
            printBoard();
            int row, col;
            cout << "Player " << (currentPlayer == ChessPiece::Black ? "Black" : "White") << ", enter your move: ";
            cin >> row >> col;

            if (isValidMove(row, col)) {
                board[row][col] = currentPlayer;
                if (isWinningMove(row, col)) {
                    printBoard();
                    cout << "Player " << (currentPlayer == ChessPiece::Black ? "Black" : "White") << " wins!" << endl;
                    break;
                }
                currentPlayer = (currentPlayer == ChessPiece::Black ? ChessPiece::White : ChessPiece::Black);
            } else {
                cout << "Invalid move. Try again." << endl;
            }
        }
    }

private:
    vector<vector<ChessPiece>> board;
    ChessPiece currentPlayer;

    bool isValidMove(int row, int col) {
        if (row < 0 || row >= SIZE || col < 0 || col >= SIZE) {
            return false;
        }
        if (board[row][col] != ChessPiece::None) {
            return false;
        }
        return true;
    }

    bool isWinningMove(int row, int col) {
        int dx[] = {1, 0, 1, 1};
        int dy[] = {0, 1, 1, -1};

        for (int i = 0; i < 4; i++) {
            int count = 1;
            for (int j = 1; j < 5; j++) {
                int newRow = row + dx[i] * j;
                int newCol = col + dy[i] * j;
                if (newRow < 0 || newRow >= SIZE || newCol < 0 || newCol >= SIZE || board[newRow][newCol] != currentPlayer) {
                    break;
                }
                count++;
            }
            if (count == 5) {
                return true;
            }
        }
        return false;
    }

    void printBoard() {
        for (int i = 0; i < SIZE; i++) {
            for (int j = 0; j < SIZE; j++) {
                switch (board[i][j]) {
                    case ChessPiece::None:
                        cout << ".";
                        break;
                    case ChessPiece::Black:
                        cout << "X";
                        break;
                    case ChessPiece::White:
                        cout << "O";
                        break;
                }
            }
            cout << endl;
        }
    }
};

int main() {
    GobangGame game;
    game.play();
    return 0;
}

这个代码实现了一个简单的五子棋游戏。玩家可以通过输入行和列的坐标来下棋，游戏会检查是否有玩家获胜。游戏使用二维向量来表示棋盘，并使用枚举类型ChessPiece来表示棋子。play()方法是游戏的主循环，isValidMove()方法用于检查是否是有效的落子位置，isWinningMove()方法用于检查是否有玩家获胜，printBoard()方法用于打印当前棋盘状态。在main()函数中创建游戏对象并开始游戏
