用C++写一个扫雷程序

好的，下面是一个简单的扫雷程序示例：

#include <iostream>
#include <vector>
#include <time.h>
using namespace std;

class MineSweeper {
private:
    int row;
    int col;
    int mineNum;
    vector<vector<int>> board;  // 记录每个格子的状态，0-未翻开，1-已翻开，2-标记为地雷，3-标记为问号
    vector<vector<bool>> mine;  // 记录每个格子是否是地雷

public:
    MineSweeper(int r, int c, int m) : row(r), col(c), mineNum(m) {
        board.resize(row, vector<int>(col, 0));
        mine.resize(row, vector<bool>(col, false));
        srand((unsigned int)time(NULL));
        while (mineNum > 0) {  // 随机布雷
            int x = rand() % row;
            int y = rand() % col;
            if (!mine[x][y]) {
                mine[x][y] = true;
                mineNum--;
            }
        }
    }

    void printBoard() {  // 打印游戏界面
        cout << "    ";
        for (int j = 0; j < col; j++) {
            cout << j << " ";
        }
        cout << endl;
        cout << "   ";
        for (int j = 0; j < col; j++) {
            cout << "--";
        }
        cout << endl;
        for (int i = 0; i < row; i++) {
            cout << i << " | ";
            for (int j = 0; j < col; j++) {
                if (board[i][j] == 0) {
                    cout << ". ";
                } else if (board[i][j] == 1) {
                    if (mine[i][j]) {
                        cout << "* ";
                    } else {
                        int cnt = countMine(i, j);
                        cout << (cnt > 0 ? to_string(cnt) : " ") << " ";
                    }
                } else if (board[i][j] == 2) {
                    cout << "@ ";
                } else if (board[i][j] == 3) {
                    cout << "? ";
                }
            }
            cout << "|" << endl;
        }
        cout << "   ";
        for (int j = 0; j < col; j++) {
            cout << "--";
        }
        cout << endl;
    }

    void play(int x, int y) {  // 玩家翻开一个格子
        if (board[x][y] == 1 || board[x][y] == 2) {  // 已经翻开或标记为地雷，不能再操作
            return;
        }
        if (mine[x][y]) {  // 翻开的是地雷，游戏结束
            board[x][y] = 1;
            printBoard();
            cout << "Game Over!" << endl;
            return;
        }
        board[x][y] = 1;
        int cnt = countMine(x, y);
        if (cnt == 0) {  // 周围没有地雷，递归翻开周围的格子
            for (int i = -1; i <= 1; i++) {
                for (int j = -1; j <= 1; j++) {
                    if (x + i >= 0 && x + i < row && y + j >= 0 && y + j < col && !(i == 0 && j == 0)) {
                        play(x + i, y + j);
                    }
                }
            }
        }
        printBoard();
    }

    void mark(int x, int y) {  // 玩家标记一个格子为地雷或问号
        if (board[x][y] == 1) {  // 已经翻开，不能再操作
            return;
        }
        if (board[x][y] == 2) {  // 已经标记为地雷，改为问号
            board[x][y] = 3;
        } else if (board[x][y] == 3) {  // 已经标记为问号，改为未翻开
            board[x][y] = 0;
        } else {  // 未标记，改为地雷
            board[x][y] = 2;
        }
        printBoard();
    }

private:
    int countMine(int x, int y) {  // 统计周围的地雷数量
        int cnt = 0;
        for (int i = -1; i <= 1; i++) {
            for (int j = -1; j <= 1; j++) {
                if (x + i >= 0 && x + i < row && y + j >= 0 && y + j < col && mine[x + i][y + j]) {
                    cnt++;
                }
            }
        }
        return cnt;
    }
};

int main() {
    int row, col, mineNum;
    cout << "Please input the row number of the board: ";
    cin >> row;
    cout << "Please input the column number of the board: ";
    cin >> col;
    cout << "Please input the number of mines: ";
    cin >> mineNum;
    MineSweeper game(row, col, mineNum);
    game.printBoard();
    while (true) {
        int x, y;
        char op;
        cout << "Please input the operation (P-play, M-mark): ";
        cin >> op;
        cout << "Please input the row and column number of the cell: ";
        cin >> x >> y;
        if (op == 'P') {
            game.play(x, y);
        } else if (op == 'M') {
            game.mark(x, y);
        }
    }
    return 0;
}

该程序实现了基本的扫雷游戏功能，包括随机布雷、打印游戏界面、玩家翻开格子、统计周围地雷数量、递归翻开周围的格子、玩家标记格子为地雷或问号等。程序使用了对象-oriented 的设计思想，将游戏逻辑封装在 MineSweeper 类中，方便调用和维护。
