Thread: Please help! Stuck on card dealing program.

I am stuck! This isn't running...any help would be greatly appreciated. Thanks!

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void shuffle( int [] [13] );
void deal(const int [] [13], const char *[], const char *[] );
void countface( int [],const char*[]);
void countsuit(int [],const char*[]);
int getface(int);
int getsuit(int);

int main()
{
	const char *suit[4] =
	{ "Hearts", "Diamonds","Clubs", "Spades"};
	const char *face[13] =
	{"Ace","Deuce","Three","Four","Five","Six","Seven","Eight","Nine","Ten","Jack","Queen","King"};
	int deck[4][13] = {0};
	int hand[]={5};

	srand( time(0) );

	shuffle( deck);
	deal(deck,face,suit);
	countface(hand,face);
	countsuit(hand,suit);

	return 0;
}

void shuffle(int wDeck[][13])
{
	int row,column,card;

	for (card=1;card<= 52; card++){
		do{
			row= rand() % 4;
			column = rand() % 13;
		} while(wDeck[row][column] != 0);

		wDeck[row][column] = card;
}	

}
void deal(const int wDeck[][13], const char *wFace[],
		  const char *wSuit[] )
{
	int card,row,column;

	for (card=1;card<=5;card++)
		for (row=0;row <=3;row++)
			for (column=0;column<=12;column++)

				if (wDeck[row][column]== card)
					printf("%5s of %-8s%c\n\n",
					wFace[column],wSuit[row],
					card % 2 == 0? '\n' : '\t' );
}
void countface(int hand[],const char *wFace[])
{
	int value,count;
	int store[13] = {0};

	for (count=0;count<5;count++)
	{
		value=getface(hand[count]);
		++store[value];
	   if (store[value]==2)
		   printf("You have a pair!");
	   else if (store[value]==3)
		   printf("You have three of a kind!\n");
	   else if(store[value]==4)
		   printf("You have four of a kind!\n");
	}
}
void countsuit(int hand[],const char *wSuit[])
{
	int value,count;
	int store[4] = {0};

	for (count=0;count<5;count++)
	{
		value=getsuit(hand[count]);
		++store[value];
	   if (store[value]==5)
		   printf("You have a flush!!\n\n");
	}
	
}
int getface(int Card)
{
	return (Card-1)%13;
}
int getsuit(int Card)
{
	return (Card-1)/13;
}

Code:

void shuffle(int wDeck[][13])
{
	int row,column,card;

	for (card=1;card<= 52; card++){
		do{
			row= rand() % 4;
			column = rand() % 13;
		} while(wDeck[row][column] != 0);

		wDeck[row][column] = card;
}	

}

This is a very bad and slow way to shuffle a deck.

This is faster way to randomize an array

Code:

for (i = 0; i < n; ++i) {
       swap(&A[i], &A[rand() % (n - i) + i]
}
