在C ++中实现一张卡片 [英] Implementing a Deck of Cards in C++

问题描述

所以我想创建一副卡片，我还是一个新的C ++和指针，所以我有几个问题

所以我有 Card class getRank ， getSuit c $ c>卡对象。
他们的方式，我设置的甲板是1-13号为排名和1-4为西装。所以这是一个简单的比较，通过比较一张卡的排名+西装和另一张卡的排名+西装。

所以我初始化并声明了两个数组，如下：

  char Rank [13] = {1，... 13}; 
 char Suit [4] = ... 
  

/ p>

  char * getSuit（）{return Suit; } 
 char * getRank（）{return Rank; } 
 int Comp（Card * card）{
 if（rank + suit< card-> rank + card-> suit）
 return 1; 
 else if ... 
 else ... 
} 
  

我的问题是，是一个坏主意，有一个字符数组，因为我只存储整数？
后来我计划把这些数字输出三锹，这就是为什么我用char。

我的其他问题是，我的get方法看起来不错吗？ get方法，将返回整个数组或数组的索引，这是我想要的。

我仍然在绘制过程中，这就是为什么我只有代码片段

 
 
 code> class Card 
 {
 public：
 // TODO：提供合适的构造函数... 
 
枚举Suit {Hearts，Diamonds，Clubs，Spades }; 
枚举Rank {A，K，Q，J，_10，_9，_8，_7，_6，_5，_4，_3，_2} 
 
 Suit getSuit（）{return suit; } 
 Rank getRank（）{return rank; } 
 
 // TODO：实现setters等等... 
 
 bool operator ==（const Card& c）const 
 {
 return rank == c.rank&& suit == c.suit; 
} 
 
 private：
西装; 
排名; 
}; 
  

所以我建议你使用枚举并使用准确的比较标准来比较两张牌。

类似地，可以实现operator>和operator <根据你的游戏规则和逻辑。

你有想法...

So I am trying to create a deck of cards and I am still kind of new to C++ and pointers so I have a few question

So I have Card class with getRank, getSuit, and comparison of two Card objects. They way I'm setting the deck is number 1-13 for the rank and 1-4 for the suit. So it's a simple compare by comparing one Card's rank+suit with another card's rank+suit.

So i initialize and declared the two arrays like this:

char Rank[13] = {1,...13};
char Suit[4] = ...

and my methods are like this:

char* getSuit(){ return Suit; }
char* getRank(){ return Rank; }
int Comp(Card *card) {
    if (rank+suit < card->rank+card->suit)
        return 1;
    else if...
    else ...
}

My question is, is it a bad idea to have a char array since i'm only storing integers? Later on i plan on converting these numbers to output "Three Spade" which is why i used char.

my other question is, does my get methods look right? The get methods, would it be returning the whole array or a index of the array, which is what I want. And am I using '->' correctly?

I still in the drawing process which is why i only have snippets of code

解决方案

Here is some draft for you to consider and probably build your class upon it:

class Card
{
public:
   // TODO: provide suitable constructor...

   enum Suit {Hearts, Diamonds, Clubs, Spades};
   enum Rank {A, K, Q, J, _10, _9, _8, _7, _6, _5, _4, _3, _2};

   Suit getSuit() { return suit; }
   Rank getRank() { return rank; }

   // TODO: implement setters, etc...

   bool operator==(const Card& c) const
   {
      return rank == c.rank && suit == c.suit;
   }

private:
   Suit suit;
   Rank rank;
};

So I suggest you to use enums and use exact comparison criterion to compare two cards.
Similarly you can implement operator> and operator< according to your game rules and logic.

You got the idea...
