Question

大家好，我试图写一场战争游戏，但我的代码会产生永无止境的游戏。当我看到输出时，我看到有一个循环，其中玩家1和玩家2交替赢得轮次。评估谁应该获胜看起来是正确的。几乎看起来像玩家一和玩家双手均匀匹配。我在比赛开始之前一直在洗牌，所以我不知道这是怎么回事。我不确定这里发生了什么。我也使用c ++ 98。

using namespace std;

#define SSTR( x ) static_cast< std::ostringstream & >( \
        ( std::ostringstream() << std::dec << x ) ).str()

void shuffleDeck(vector<string> &);

void splitDeck(vector<string> vDeck, vector<string> &, vector<string> &);

int compareRound(char, char);

int main(int argc, char** argv) {
vector<string> vPlayerOneCards;
vector<string> vPlayerTwoCards;

vector<string> vDeck;
for (int i = 2; i < 15; i++){
    for (int e = 0; e < 4; e++){
        string currentCard;
        if (i < 11){
            currentCard += SSTR( i ).c_str();
        }
        else if (i == 11){
            currentCard += "Jack";
        }
        else if (i == 12){
            currentCard += "Queen";
        }
        else if (i == 13){
            currentCard += "King";
        }
        else if (i == 14){
            currentCard += "Ace";
        }

        currentCard += " of ";

        if (e == 0){
            currentCard += "Hearts";
        }
        else if (e == 1){
            currentCard += "Diamonds";
        }
        else if (e == 2){
            currentCard += "Clubs";
        }
        else if (e == 3){

嘿我弄明白我做错了什么。在我取消正在全面播放的两张牌之前，我正在为获胜者手牌添加牌。更改此功能后，每件事情都开始正常工作。

    cardPool.push_back(vPlayerTwoCards[0]);
    cardPool.push_back(vPlayerOneCards[0]);
    vPlayerOneCards.erase(vPlayerOneCards.begin());
    vPlayerTwoCards.erase(vPlayerTwoCards.begin());

    cout << "Player One: " + vPlayerOneCards[0] + "." << endl << "VS" << endl << "Player Two: " + vPlayerTwoCards[0] + "." << endl;

    int roundWinner = compareRound(vPlayerOneCards[0][0], vPlayerTwoCards[0][0]);
    if (roundWinner == 0){
        cout << "Player One Wins The Round." << endl;
        while (cardPool.size() > 0){
            vPlayerOneCards.push_back(cardPool[cardPool.size()-1]);
            cardPool.erase(cardPool.end());
        }
    }
    else if (roundWinner == 1){
        cout << "Player Two Wins The Round." << endl;
        while (cardPool.size() > 0){
            vPlayerTwoCards.push_back(cardPool[cardPool.size()-1]);
            cardPool.erase(cardPool.end());
        }
    }
    else {
        cout << "The Round Is A Tie." << endl;
    }
    cout << endl;

    cout << vPlayerOneCards.size() << endl;
    cout << vPlayerTwoCards.size() << endl;

永远不会结束的战争游戏
