用c++写一个五子棋游戏代码

好的，以下是一个简单的 C++ 五子棋游戏代码：

#include <iostream>
using namespace std;

const int BOARD_SIZE = 15; // 定义棋盘大小

enum Piece { EMPTY = 0, BLACK = 1, WHITE = 2 }; // 定义棋子类型

class Board {
public:
    Board() { // 初始化棋盘
        for (int i = 0; i < BOARD_SIZE; i++) {
            for (int j = 0; j < BOARD_SIZE; j++) {
                board[i][j] = EMPTY;
            }
        }
    }

    void print() { // 打印棋盘
        cout << "  ";
        for (int i = 0; i < BOARD_SIZE; i++) {
            cout << i << " ";
        }
        cout << endl;
        for (int i = 0; i < BOARD_SIZE; i++) {
            cout << i << " ";
            for (int j = 0; j < BOARD_SIZE; j++) {
                switch (board[i][j]) {
                case EMPTY:
                    cout << ". ";
                    break;
                case BLACK:
                    cout << "X ";
                    break;
                case WHITE:
                    cout << "O ";
                    break;
                }
            }
            cout << endl;
        }
    }

    bool canMove(int row, int col) { // 判断该位置是否可以落子
        if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE) {
            return false;
        }
        if (board[row][col] != EMPTY) {
            return false;
        }
        return true;
    }

    bool move(int row, int col, Piece piece) { // 落子
        if (!canMove(row, col)) {
            return false;
        }
        board[row][col] = piece;
        return true;
    }

    bool isWin(int row, int col, Piece piece) { // 判断是否胜利
        // 水平方向
        int count = 1;
        for (int i = col - 1; i >= 0; i--) { // 左边
            if (board[row][i] == piece) {
                count++;
            } else {
                break;
            }
        }
        for (int i = col + 1; i < BOARD_SIZE; i++) { // 右边
            if (board[row][i] == piece) {
                count++;
            } else {
                break;
            }
        }
        if (count >= 5) {
            return true;
        }

        // 垂直方向
        count = 1;
        for (int i = row - 1; i >= 0; i--) { // 上面
            if (board[i][col] == piece) {
                count++;
            } else {
                break;
            }
        }
        for (int i = row + 1; i < BOARD_SIZE; i++) { // 下面
            if (board[i][col] == piece) {
                count++;
            } else {
                break;
            }
        }
        if (count >= 5) {
            return true;
        }

        // 左上到右下方向
        count = 1;
        for (int i = row - 1, j = col - 1; i >= 0 && j >= 0; i--, j--) { // 左上
            if (board[i][j] == piece) {
                count++;
            } else {
                break;
            }
        }
        for (int i = row + 1, j = col + 1; i < BOARD_SIZE && j < BOARD_SIZE; i++, j++) { // 右下
            if (board[i][j] == piece) {
                count++;
            } else {
                break;
            }
        }
        if (count >= 5) {
            return true;
        }

        // 右上到左下方向
        count = 1;
        for (int i = row - 1, j = col + 1; i >= 0 && j < BOARD_SIZE; i--, j++) { // 右上
            if (board[i][j] == piece) {
                count++;
            } else {
                break;
            }
        }
        for (int i = row + 1, j = col - 1; i < BOARD_SIZE && j >= 0; i++, j--) { // 左下
            if (board[i][j] == piece) {
                count++;
            } else {
                break;
            }
        }
        if (count >= 5) {
            return true;
        }

        return false;
    }

private:
    Piece board[BOARD_SIZE][BOARD_SIZE];
};

int main() {
    Board board;
    Piece turn = BLACK;
    while (true) {
        board.print();

        int row, col;
        cout << "Player " << (turn == BLACK ? "X" : "O") << " move (row col): ";
        cin >> row >> col;

        if (!board.move(row, col, turn)) {
            cout << "Invalid move!" << endl;
            continue;
        }

        if (board.isWin(row, col, turn)) {
            cout << "Player " << (turn == BLACK ? "X" : "O") << " wins!" << endl;
            break;
        }

        turn = (turn == BLACK ? WHITE : BLACK);
    }
    return 0;
}

这个五子棋游戏代码实现了基本的落子、胜负判断和打印棋盘功能，但是还有很多可以改进的地方，比如增加悔棋功能、实现人机对战等等。
