写一个五子棋的c++代码

以下是基本的五子棋 C++ 代码，包括棋盘的绘制、用户输入、落子和判断胜负等功能：

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

const int MAXN = 15;
char board[MAXN][MAXN];  // 棋盘
int n = 10;  // 棋盘大小

// 绘制棋盘
void draw_board() {
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n; j++) {
            cout << board[i][j] << " ";
        }
        cout << endl;
    }
}

// 判断胜负
bool check_win(char c) {
    // 判断行
    for (int i = 0; i < n; i++) {
        int cnt = 0;
        for (int j = 0; j < n; j++) {
            if (board[i][j] == c) cnt++;
            else cnt = 0;
            if (cnt >= 5) return true;
        }
    }
    // 判断列
    for (int j = 0; j < n; j++) {
        int cnt = 0;
        for (int i = 0; i < n; i++) {
            if (board[i][j] == c) cnt++;
            else cnt = 0;
            if (cnt >= 5) return true;
        }
    }
    // 判断对角线
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n; j++) {
            int cnt = 0;
            for (int k = 0; k < 5 && i+k<n && j+k<n; k++) {
                if (board[i+k][j+k] == c) cnt++;
                else break;
                if (cnt >= 5) return true;
            }
            cnt = 0;
            for (int k = 0; k < 5 && i+k<n && j-k>=0; k++) {
                if (board[i+k][j-k] == c) cnt++;
                else break;
                if (cnt >= 5) return true;
            }
        }
    }
    return false;
}

int main() {
    memset(board, '.', sizeof(board));  // 初始化棋盘
    draw_board();  // 绘制棋盘
    char player = 'X';  // 先手为 X
    while (true) {
        cout << "Player " << player << " turn:" << endl;
        int x, y;
        cin >> x >> y;
        if (x < 0 || x >= n || y < 0 || y >= n || board[x][y] != '.') {
            cout << "Invalid move!" << endl;
            continue;
        }
        board[x][y] = player;  // 落子
        draw_board();  // 绘制棋盘
        if (check_win(player)) {
            cout << "Player " << player << " wins!" << endl;
            break;
        }
        // 交换玩家
        player = (player == 'X' ? 'O' : 'X');
    }
    return 0;
}

这只是一个基本的五子棋代码，你可以根据需求进行修改和扩展。
