// Creat human deck
vector<CardDeck> humanDeck(26);

    humanDeck[i] = startDeck[i];

}

// Creat computer deck
vector<CardDeck> computerDeck(26);

{
    computerDeck[i] = startDeck[i + 26];

}

cout << "The second computer card is " << computerDeck[1].getValue() << " of " << computerDeck[1].getSuit() << "\n\n";



getchar();
return 0;

} // end main

// Functions for CardDeck class
CardDeck::CardDeck(int theValue, string theSuit)
{
value = theValue;
suit = theSuit;
}

void CardDeck::setValue(int theValue)
{
value = theValue;
}

void CardDeck::setSuit(string theSuit)
{
suit = theSuit;
}

int CardDeck::getValue()
{
return value;
}

string CardDeck::getSuit()
{
return suit;
}

显然游戏还没有完成，而且我是C ++和编程的新手，所以任何帮助都可以

我想要一些帮助，弄清楚如何只获取正数而不是负数。 还想弄清楚为什么它们返回的前两个输出值总是相同。

• 谢谢

Answer 1

您可能打算这样做：

for (i = 0; i < 13; i++)
{
    startDeck[i].setValue(i+1);
    startDeck[i].setSuit("Dragons");
    //startDeck[i].setValue(i+1);
    //  startDeck[i].setSuit("Dragons");
}

否则，请startDeck[i].setValue(i-12); 将为i <12设置负值，这是该循环的大部分时间。

我想知道为什么您那里有正确的代码并注释掉了……这是什么问题？
