对于一项家庭作业,我需要创建一个程序让您玩爱尔兰纸牌游戏25。我可以让我的代码向一个人伸出援手,但是如果我尝试有多个人,则该代码会给出和其他人一模一样。我该如何向他人提供独特的帮助?
我尝试使用循环,认为该函数只会重置数组,但没有重置
/* Deals a random hand of cards */
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define TRUE 1
#define FALSE 0
#define BOOL int
#define NUM_SUITS 4
#define NUM_RANKS 13
int DealCards(int i);
int main()
{
int i;
int NumOfPlayers;
printf("Please Enter the Number Of Players: ");
scanf("%d", &NumOfPlayers);
for (i = 1; i <= NumOfPlayers; i++)
{
DealCards(i);
}
}
int DealCards(int i)
{
BOOL in_hand[NUM_SUITS][NUM_RANKS] = { FALSE };
int num_cards = 5, rank, suit;
const char rank_code[] = { '2', '3', '4', '5', '6', '7', '8',
'9', '10', '11', '12', '13', 'A' };
const char suit_code[] = { 'C', 'D', 'H', 'S' };
srand(time(NULL));
printf("\n\nPlayer %d's hand :\n", i);
while (num_cards > 0)
{
suit = rand() % NUM_SUITS;
rank = rand() % NUM_RANKS;
if (!in_hand[suit][rank])
{
in_hand[suit][rank] = TRUE;
num_cards--;
printf(" %cof%c ", rank_code[rank], suit_code[suit]);
}
printf("\n");
}
return 0;
}
答案 0 :(得分:3)
问题是您在向每位玩家发牌之前调用了srand()
函数。您使用time(NULL)
作为参数,因此种子仅每秒改变一次,玩家获得具有相同种子的牌。
您只需为每个程序启动设置一次种子即可。
答案 1 :(得分:3)
您当前的方法是抽签更换卡片,然后检查是否已抽签。 shuffle
这套游戏非常简单,并且是一个更好的游戏模型。
您应该做的是定义一个对特定卡进行编码的类型,使用该卡中的每个值填充该类型的集合,对卡组进行洗牌,然后从经过洗牌的卡套分配卡。
作为草图
#include <vector>
#include <string>
#include <random>
#include <algorithm>
#include <iostream>
const std::vector<std::string> rank_code = { "2","3","4","5","6","7","8","9","10","Jack","Queen","King","Ace" };
const std::vector<std::string> suit_code = { "Clubs","Diamonds","Hearts","Spades" };
const int num_cards = 5;
struct Card
{
Card(char s, char r) : suit(s), rank(r) {}
char suit;
char rank;
};
std::ostream & operator<< (std::ostream & os, const Card & c)
{
return os << rank_code[c.rank] << " of " << suit_code[c.suit];
}
using Deck = std::vector<Card>;
Deck freshDeck()
{
Deck result;
for (std::size_t s = 0; s < suit_code.size(); ++s)
for (std::size_t r = 0; r < rank_code.size(); ++r)
result.emplace_back(s, r);
return result;
}
void dealCards(int player, Deck & deck)
{
std::string joiner;
std::cout << std::endl << "Player " << player << "'s hand" << std::endl;
for (int c = 0; c < num_cards; ++c)
{
std::cout << joiner << deck.back();
deck.pop_back();
joiner = ", ";
}
std::cout << std::endl;
}
int main ()
{
std::mt19937 gen{ std::random_device{}() };
Deck deck = freshDeck();
std::shuffle(deck.begin(), deck.end(), gen);
std::cout << "Enter number of players" << std::endl;
int num_players;
std::cin >> num_players;
for (int p = 1; p <= num_players; ++p)
{
dealCards(p, deck);
}
}
答案 2 :(得分:1)
在赠送卡片之前只需初始化您的srand(time(NULL))
unsigned int length
答案 3 :(得分:0)
问题是srand
每次运行时都用相同的值初始化。
因此,以相同的顺序生成相同的随机值。这就是为什么所有的手都一样的原因。
srand
和rand
来自<cstdlib>
标头。
在C ++ 11和更高版本中,最好使用<random>
标头中的函数。
C ++还为使用面向对象的编程提供了许多可能性,并且具有广泛的数据结构和算法库。我建议使用std::vector
或std::array
而不是普通数组。并且还可以使用std::shuffle
来随机抽取卡片。
