需要C项目的帮助 [英] Need help with a C project

问题描述

我正在用C做一个大学项目的纸牌游戏。我基本上必须创建一个有2种卡类型的游戏，Card和CardDeck，写一个功能来洗牌，并在2个玩家之间发出8张牌。

我还需要能够允许用户输入他们想要使用的套牌数量，所以我认为我不能使用固定大小的数组，也许就像动态一样内存分配。

任何帮助都会非常感激。



我尝试了什么：

I'm doing a Card game in C for a university project. I basically have to create a game that has 2 card types,"Card" and "CardDeck", write a function to shuffle them and give out 8 cards between 2 players.
I also need to be able to allow the user to input the amount of decks they want to use, so I don't think I would be able to use a fixed size array, maybe like a dynamic memory allocation.
Any help would be much appreciated.

What I have tried:

#include <stdio.h>

//Data Type Card

enum suit
{
	Club, Spade, Heart, Diamond
};

typedef enum suit Suit;

enum rank
{
	Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King, Ace 
};
typedef enum rank Rank;

struct card
{
Suit c_suit;
Rank c_rank;
};

typedef struct card Card;
void shuffle(Card * deck);

void shuffle(Card * deck)
{
    int temp;
    int y, x, t=0;  
    for (x = 52; x > 0 ; x--)
    { 
        y = rand() % x;   
        temp = deck[x];
        deck[x] = deck[y];
        deck[y] = temp;
    }

}

有两个问题：

There are two problems:

1. 数组索引从C / C ++开始为零，但是你从52循环到1
2. 使用 rand （）％x 可能无法给出预期的结果

1. Array indexes start at zero with C/C++ but you are looping from 52 to 1
2. Using rand() % x might not give the expected results

假设传递的 deck 数组的大小为52，你必须在0到51的范围内循环。



使用％模数运算符 rand（）返回0到 x - 1 。因为 x 是你的循环变量，所以当x == 1时，可用范围将变小，直到结果变为1.



正确的实现可能是：



Assuming that the passed deck array has a size of 52, you must loop within the range of 0 to 51.

Using the % modulo operator with rand() returns a random value in the range 0 to x - 1. Because x is your loop variable, the available range will get smaller until the result becomes 1 when x == 1.

A proper implementation might be:

void shuffle(Card * deck)
{
    int temp;
    int y, x;
    for (x = 0; x < 52 ; x++)
    {
        y = rand() % 52;
        temp = deck[x];
        deck[x] = deck[y];
        deck[y] = temp;
    }
}
