c++五子棋

好的，这是一个简单的C++五子棋代码示例，您可以参考：

#include <iostream>
using namespace std;

// 定义棋盘大小
const int BOARD_SIZE = 15;

// 定义棋盘中的棋子类型
enum ChessType {
    EMPTY,
    BLACK,
    WHITE
};

// 定义棋盘类
class ChessBoard {
public:
    // 构造函数
    ChessBoard() {
        for (int i = 0; i < BOARD_SIZE; i++) {
            for (int j = 0; j < BOARD_SIZE; j++) {
                board[i][j] = EMPTY;
            }
        }
    }
    
    // 下棋函数
    bool PlaceChess(int x, int y, ChessType type) {
        if (x < 0 || x >= BOARD_SIZE || y < 0 || y >= BOARD_SIZE || board[x][y] != EMPTY) {
            return false;   // 落子位置不合法或已经有棋子
        }
        board[x][y] = type;
        return true;
    }
    
    // 判断胜负函数
    bool CheckWin(int x, int y, ChessType type) {
        // 判断横向
        int count = 1;
        for (int i = x - 1; i >= 0 && board[i][y] == type; i--) {
            count++;
        }
        for (int i = x + 1; i < BOARD_SIZE && board[i][y] == type; i++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        
        // 判断纵向
        count = 1;
        for (int j = y - 1; j >= 0 && board[x][j] == type; j--) {
            count++;
        }
        for (int j = y + 1; j < BOARD_SIZE && board[x][j] == type; j++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        
        // 判断左上到右下斜线
        count = 1;
        for (int i = x - 1, j = y - 1; i >= 0 && j >= 0 && board[i][j] == type; i--, j--) {
            count++;
        }
        for (int i = x + 1, j = y + 1; i < BOARD_SIZE && j < BOARD_SIZE && board[i][j] == type; i++, j++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        
        // 判断左下到右上斜线
        count = 1;
        for (int i = x - 1, j = y + 1; i >= 0 && j < BOARD_SIZE && board[i][j] == type; i--, j++) {
            count++;
        }
        for (int i = x + 1, j = y - 1; i < BOARD_SIZE && j >= 0 && board[i][j] == type; i++, j--) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        
        return false;
    }
    
    // 打印棋盘函数
    void DrawBoard() {
        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++) {
                if (board[i][j] == EMPTY) {
                    cout << "+ ";
                } else if (board[i][j] == BLACK) {
                    cout << "X ";
                } else {
                    cout << "O ";
                }
            }
            cout << endl;
        }
    }

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

int main() {
    ChessBoard board;
    int x, y;
    ChessType type = BLACK;
    while (true) {
        board.DrawBoard();
        cout << (type == BLACK ? "Black" : "White") << "'s turn. Input x,y to place chess: ";
        cin >> x >> y;
        if (board.PlaceChess(x, y, type)) {
            if (board.CheckWin(x, y, type)) {
                board.DrawBoard();
                cout << (type == BLACK ? "Black" : "White") << " wins!" << endl;
                break;
            }
            type = (type == BLACK ? WHITE : BLACK);
        } else {
            cout << "Invalid position, please input again." << endl;
        }
    }
    return 0;
}

这个代码实现了五子棋游戏的基本功能，包括下棋、判断胜负和打印棋盘等。
