帮我写一段扫雷游戏代码

好的，以下是一段简单的扫雷游戏代码：

#include <iostream>
#include <vector>
#include <cstdlib>
#include <ctime>

using namespace std;

const int ROWS = 10;
const int COLS = 10;
const int MINES = 10;

vector<vector<int>> board(ROWS, vector<int>(COLS, 0));
vector<vector<bool>> revealed(ROWS, vector<bool>(COLS, false));
vector<pair<int, int>> mines(MINES);

void placeMines() {
    srand(time(NULL));
    int count = 0;
    while (count < MINES) {
        int row = rand() % ROWS;
        int col = rand() % COLS;
        if (board[row][col] != -1) {
            board[row][col] = -1;
            mines[count] = make_pair(row, col);
            count++;
        }
    }
}

void printBoard() {
    cout << "  ";
    for (int i = 0; i < COLS; i++) {
        cout << i << " ";
    }
    cout << endl;
    for (int i = 0; i < ROWS; i++) {
        cout << i << " ";
        for (int j = 0; j < COLS; j++) {
            if (revealed[i][j]) {
                if (board[i][j] == -1) {
                    cout << "* ";
                } else {
                    cout << board[i][j] << " ";
                }
            } else {
                cout << "- ";
            }
        }
        cout << endl;
    }
}

int countMines(int row, int col) {
    int count = 0;
    for (int i = -1; i <= 1; i++) {
        for (int j = -1; j <= 1; j++) {
            int r = row + i;
            int c = col + j;
            if (r >= 0 && r < ROWS && c >= 0 && c < COLS && board[r][c] == -1) {
                count++;
            }
        }
    }
    return count;
}

void reveal(int row, int col) {
    if (board[row][col] == -1) {
        cout << "Game over!" << endl;
        printBoard();
        exit(0);
    }
    revealed[row][col] = true;
    if (countMines(row, col) == 0) {
        for (int i = -1; i <= 1; i++) {
            for (int j = -1; j <= 1; j++) {
                int r = row + i;
                int c = col + j;
                if (r >= 0 && r < ROWS && c >= 0 && c < COLS && !revealed[r][c]) {
                    reveal(r, c);
                }
            }
        }
    }
}

int main() {
    placeMines();
    printBoard();
    while (true) {
        int row, col;
        cout << "Enter row and column: ";
        cin >> row >> col;
        reveal(row, col);
        printBoard();
    }
    return 0;
}

这段代码实现了一个简单的扫雷游戏，玩家可以输入行和列来揭开对应的方块，如果揭开的方块是地雷，游戏结束。如果揭开的方块周围没有地雷，会自动揭开周围的方块。
