自定义代表扑克牌的Card类(包括花色和牌面值),为Card类提供自定义的比较大小运算符支持,大小比较的标准是先比较牌面值,如果牌面值相等则比较花色,花色大小规则为:黑桃>红心>草花>方块。

下面是一个简单的Card类的实现,其中包括花色和牌面值的定义,以及自定义的比较大小运算符:
```cpp
#include <iostream>
#include <string>
using namespace std;
enum Suit { SPADE, HEART, CLUB, DIAMOND };
enum Rank { ACE, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, TEN, JACK, QUEEN, KING };
class Card {
public:
Card(Suit s, Rank r) : suit(s), rank(r) {}
bool operator<(const Card& other) const {
if (rank != other.rank) {
return rank < other.rank;
} else {
return suit < other.suit;
}
}
string getSuit() const {
switch (suit) {
case SPADE: return "Spade";
case HEART: return "Heart";
case CLUB: return "Club";
case DIAMOND: return "Diamond";
}
return "";
}
string getRank() const {
switch (rank) {
case ACE: return "Ace";
case TWO: return "2";
case THREE: return "3";
case FOUR: return "4";
case FIVE: return "5";
case SIX: return "6";
case SEVEN: return "7";
case EIGHT: return "8";
case NINE: return "9";
case TEN: return "10";
case JACK: return "Jack";
case QUEEN: return "Queen";
case KING: return "King";
}
return "";
}
private:
Suit suit;
Rank rank;
};
int main() {
Card c1(SPADE, ACE);
Card c2(HEART, QUEEN);
Card c3(DIAMOND, KING);
Card c4(CLUB, FIVE);
cout << c1.getRank() << " of " << c1.getSuit() << endl;
cout << c2.getRank() << " of " << c2.getSuit() << endl;
cout << c3.getRank() << " of " << c3.getSuit() << endl;
cout << c4.getRank() << " of " << c4.getSuit() << endl;
if (c1 < c2) {
cout << "c1 is smaller than c2" << endl;
} else {
cout << "c1 is greater than or equal to c2" << endl;
}
if (c2 < c3) {
cout << "c2 is smaller than c3" << endl;
} else {
cout << "c2 is greater than or equal to c3" << endl;
}
if (c3 < c4) {
cout << "c3 is smaller than c4" << endl;
} else {
cout << "c3 is greater than or equal to c4" << endl;
}
return 0;
}
```
这个实现中,我们使用了两个枚举类型来定义花色和牌面值,然后定义了一个Card类来表示一张扑克牌。Card类中包括了构造函数、自定义的小于运算符和获取花色和牌面值的方法。
在小于运算符中,我们首先比较牌面值,如果两张牌的牌面值不相等,则直接返回它们的比较结果。如果牌面值相等,则比较花色,根据题目要求,我们定义了黑桃>红心>草花>方块的比较规则。
在主函数中,我们创建了四张扑克牌,并输出它们的牌面和花色。然后,我们使用自定义的小于运算符来比较这四张牌的大小关系,并输出比较结果。
注意,在实际应用中,可能需要为Card类提供更多的方法和操作符重载来支持更多的扑克牌游戏规则。
