五子棋C++人人对战代码

以下是一个简单的五子棋C++人人对战代码，使用了字符数组来表示棋盘：

#include <iostream>
#include <cstring>

using namespace std;

const int BOARD_SIZE = 15;  // 棋盘大小

char board[BOARD_SIZE][BOARD_SIZE];  // 棋盘

void printBoard() {  // 打印棋盘
    cout << " ";
    for (int i = 0; i < BOARD_SIZE; i++) {
        cout << " " << i + 1;
    }
    cout << endl;
    for (int i = 0; i < BOARD_SIZE; i++) {
        cout << i + 1 << " ";
        for (int j = 0; j < BOARD_SIZE; j++) {
            cout << board[i][j] << " ";
        }
        cout << endl;
    }
}

bool checkWin(int row, int col, char player) {  // 判断胜负
    int count = 0;
    for (int i = row; i >= 0; i--) {  // 竖直向上
        if (board[i][col] == player) {
            count++;
        } else {
            break;
        }
    }
    for (int i = row + 1; i < BOARD_SIZE; i++) {  // 竖直向下
        if (board[i][col] == player) {
            count++;
        } else {
            break;
        }
    }
    if (count >= 5) {
        return true;
    }
    count = 0;
    for (int j = col; j >= 0; j--) {  // 水平向左
        if (board[row][j] == player) {
            count++;
        } else {
            break;
        }
    }
    for (int j = col + 1; j < BOARD_SIZE; j++) {  // 水平向右
        if (board[row][j] == player) {
            count++;
        } else {
            break;
        }
    }
    if (count >= 5) {
        return true;
    }
    count = 0;
    for (int i = row, j = col; i >= 0 && j >= 0; i--, j--) {  // 左上到右下
        if (board[i][j] == player) {
            count++;
        } else {
            break;
        }
    }
    for (int i = row + 1, j = col + 1; i < BOARD_SIZE && j < BOARD_SIZE; i++, j++) {  // 左上到右下
        if (board[i][j] == player) {
            count++;
        } else {
            break;
        }
    }
    if (count >= 5) {
        return true;
    }
    count = 0;
    for (int i = row, j = col; i >= 0 && j < BOARD_SIZE; i--, j++) {  // 右上到左下
        if (board[i][j] == player) {
            count++;
        } else {
            break;
        }
    }
    for (int i = row + 1, j = col - 1; i < BOARD_SIZE && j >= 0; i++, j--) {  // 右上到左下
        if (board[i][j] == player) {
            count++;
        } else {
            break;
        }
    }
    if (count >= 5) {
        return true;
    }
    return false;
}

int main() {
    memset(board, '.', sizeof(board));  // 初始化棋盘
    printBoard();

    char player1 = 'X';  // 玩家1
    char player2 = 'O';  // 玩家2
    char currentPlayer = player1;  // 当前玩家

    int row, col;
    while (true) {
        cout << "请 " << currentPlayer << " 下棋（输入行号和列号，以空格分隔）：" << endl;
        cin >> row >> col;
        row--;
        col--;
        if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE) {
            cout << "输入错误，请重新输入！" << endl;
            continue;
        }
        if (board[row][col] != '.') {
            cout << "该位置已有棋子，请重新输入！" << endl;
            continue;
        }
        board[row][col] = currentPlayer;
        printBoard();
        if (checkWin(row, col, currentPlayer)) {
            cout << currentPlayer << " 获胜！" << endl;
            break;
        }
        if (currentPlayer == player1) {
            currentPlayer = player2;
        } else {
            currentPlayer = player1;
        }
    }

    return 0;
}

该代码实现了基本的下棋、打印棋盘和判断胜负功能，可以作为五子棋C++人人对战的参考。
