c++五子棋代码

以下是一个简单的 C++ 五子棋代码示例：

#include <iostream>
using namespace std;

const int BOARD_SIZE = 15;
const int EMPTY = 0;
const int BLACK = 1;
const int WHITE = 2;

int board[BOARD_SIZE][BOARD_SIZE];

void init_board() {
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            board[i][j] = EMPTY;
        }
    }
}

void print_board() {
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            if (board[i][j] == EMPTY) {
                cout << "+ ";
            } else if (board[i][j] == BLACK) {
                cout << "x ";
            } else if (board[i][j] == WHITE) {
                cout << "o ";
            }
        }
        cout << endl;
    }
}

bool check_win(int player) {
    // 检查横向
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j <= BOARD_SIZE - 5; j++) {
            bool win = true;
            for (int k = 0; k < 5; k++) {
                if (board[i][j + k] != player) {
                    win = false;
                    break;
                }
            }
            if (win) {
                return true;
            }
        }
    }

    // 检查纵向
    for (int i = 0; i <= BOARD_SIZE - 5; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            bool win = true;
            for (int k = 0; k < 5; k++) {
                if (board[i + k][j] != player) {
                    win = false;
                    break;
                }
            }
            if (win) {
                return true;
            }
        }
    }

    // 检查左上到右下斜线
    for (int i = 0; i <= BOARD_SIZE - 5; i++) {
        for (int j = 0; j <= BOARD_SIZE - 5; j++) {
            bool win = true;
            for (int k = 0; k < 5; k++) {
                if (board[i + k][j + k] != player) {
                    win = false;
                    break;
                }
            }
            if (win) {
                return true;
            }
        }
    }

    // 检查左下到右上斜线
    for (int i = 4; i < BOARD_SIZE; i++) {
        for (int j = 0; j <= BOARD_SIZE - 5; j++) {
            bool win = true;
            for (int k = 0; k < 5; k++) {
                if (board[i - k][j + k] != player) {
                    win = false;
                    break;
                }
            }
            if (win) {
                return true;
            }
        }
    }

    return false;
}

int main() {
    init_board();
    int player = BLACK;
    while (true) {
        print_board();
        int x, y;
        cout << "Player " << player << " enter your move (x y): ";
        cin >> x >> y;
        if (x < 0 || x >= BOARD_SIZE || y < 0 || y >= BOARD_SIZE) {
            cout << "Invalid move!" << endl;
            continue;
        }
        if (board[x][y] != EMPTY) {
            cout << "Invalid move!" << endl;
            continue;
        }
        board[x][y] = player;
        if (check_win(player)) {
            cout << "Player " << player << " wins!" << endl;
            break;
        }
        player = 3 - player; // 切换玩家
    }
    print_board();
    return 0;
}

这个代码实现了：

1. 初始化棋盘
2. 打印棋盘
3. 检查是否获胜
4. 循环交替让两个玩家下棋，直到有人获胜
