帮我写一个五子棋的c++代码

当然，下面是一个简单的五子棋游戏的C++代码示例：

#include <iostream>
#include <vector>

const int BOARD_SIZE = 15;
const char EMPTY = '-';
const char PLAYER_ONE = 'X';
const char PLAYER_TWO = 'O';

std::vector<std::vector<char>> board(BOARD_SIZE, std::vector<char>(BOARD_SIZE, EMPTY));

void printBoard() {
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            std::cout << board[i][j] << " ";
        }
        std::cout << std::endl;
    }
}

bool isFull() {
    for (int i = 0; i < BOARD_SIZE; i++) {
        for (int j = 0; j < BOARD_SIZE; j++) {
            if (board[i][j] == EMPTY) {
                return false;
            }
        }
    }
    return true;
}

bool checkWin(char player) {
    // 检查行
    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;
            }
        }
    }

    // 检查列
    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[j + k][i] != player) {
                    win = false;
                    break;
                }
            }
            if (win) {
                return true;
            }
        }
    }

    // 检查主对角线
    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;
            }
        }
    }

    // 检查副对角线
    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;
}

bool makeMove(int row, int col, char player) {
    if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE || board[row][col] != EMPTY) {
        return false;
    }

    board[row][col] = player;
    return true;
}

int main() {
    char currentPlayer = PLAYER_ONE;

    while (true) {
        std::cout << "当前棋盘：" << std::endl;
        printBoard();

        int row, col;
        std::cout << "玩家 " << currentPlayer << "，请输入要落子的坐标（行 列）：";
        std::cin >> row >> col;

        if (makeMove(row, col, currentPlayer)) {
            if (checkWin(currentPlayer)) {
                std::cout << "玩家 " << currentPlayer << " 获胜！" << std::endl;
                break;
            } else if (isFull()) {
                std::cout << "游戏结束，平局！" << std::endl;
                break;
            }

            currentPlayer = (currentPlayer == PLAYER_ONE) ? PLAYER_TWO : PLAYER_ONE;
        } else {
            std::cout << "无效的落子位置，请重新输入！" << std::endl;
        }
    }

    return 0;
}

这段代码实现了一个简单的五子棋游戏。玩家可以交替输入要落子的坐标（行和列），程序会根据玩家输入的位置进行落子判断，并打印出当前棋盘状态。当有一方玩家获胜或者棋盘已满时，游戏结束。注意，此代码只实现了基本的功能，还可以根据需要进行扩展和优化。
