从 vector 访问时，我的可变类的属性不会更改。(调试中)

我真的在调试这段代码时度过了一段地狱般的时光。

编写此代码是为了将棋盘上的每个玩家向前移动，直到其中一个玩家到达终点，但看起来 Player：:p osition 实际上从未更改过。我已经尝试过使用MinGW C++11和安装在带有标志-std=c++11的ubuntu遥控器上的g ++。

请提出问题或提出建议，我只是不明白。

                // Iterate through other players
                for (int i = 1; i < total_players - 1; ++i) {

                        int spaces_back = rand() % (max_penalty_spaces - min_penalty_spaces + 1) + min_penalty_spaces;
                        other_player.move(-1 * spaces_back);
                        cout << current_player.get_name() << " landed on " << other_player.get_name() << "'s space, causing ";
                        cout << other_player.get_name() << " to take a tumble and move backwards " << spaces_back << " spaces.n";
                    }
                }
                cout << current_player.get_name() << current_player.get_position() << "  " << &current_player << " - testn";

int main () {
    srand(time(NULL));
    vector<Player> players {
        Player("Jack"),
        Player("Jill")
    };

    GameBoard game{players};
    while (game.get_has_winner() != true) {
        game.move_next_player();
    }
    Player winner = game.get_last_player();
    cout << winner.get_name() << " has won!n";
    //delete[] &players;
    //delete &game;
    return 0;
}

输出也很有趣：

Jack moved forward 6 spaces to space: 7.
Jack7  0x7fffd1d9a6b0 - test
0x7fffd1d9a6b0 - test
Jill moved forward 4 spaces to space: 5.
Jill5  0x7fffd1d9a6b0 - test
0x7fffd1d9a6b0 - test
Jack moved forward 6 spaces to space: 7.
Jack7  0x7fffd1d9a6b0 - test
