如何改写程序？(语言-c++)

求用C++解答
1.现有两人玩猜拳游戏，每人可用拳头表示3种物体（石头、剪刀、布）中的一种，两人同时出拳，游戏胜负规则如下：
(1)石头vs剪刀：石头胜利。
(2)剪刀vs布：剪刀胜利。
(3)布vs石头：石头胜利。

1. 如果游戏规定比赛连续进行3次，赢2次及以上者获胜，如何改写程序？
   声明符号用的不太好求帮忙解答

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main() {
    srand(time(NULL));  // 初始化随机数生成器
    int player1_win = 0, player2_win = 0;
    while (player1_win < 2 && player2_win < 2) {  // 连续进行3次游戏，直到一方获胜
        system("cls");  // 清空屏幕
        cout << "Round " << player1_win + player2_win + 1 << endl;
        cout << "Player 1: ";
        int player1 = 0;
        cin >> player1;
        cout << "Player 2: ";
        int player2 = 0;
        cin >> player2;
        cout << endl;
        // 根据规则判断胜负
        if (player1 == player2) {
            cout << "Draw!" << endl;
        } else if ((player1 == 1 && player2 == 2) || (player1 == 2 && player2 == 3) || (player1 == 3 && player2 == 1)) {
            cout << "Player 1 wins!" << endl;
            player1_win++;
        } else {
            cout << "Player 2 wins!" << endl;
            player2_win++;
        }
        cout << "Player 1: " << player1 << endl;
        cout << "Player 2: " << player2 << endl;
        cout << "Press enter to continue...";
        cin.ignore();
        cin.get();
    }
    if (player1_win >= 2) {
        cout << "Player 1 wins the game!" << endl;
    } else {
        cout << "Player 2 wins the game!" << endl;
    }
    return 0;
}
