Modify the card shuffling and dealing program below so the shuffling and dealing

Question

Modify the card shuffling and dealing program below so the shuffling and dealing operations are performed by the same function shuffleAndDeal. The function should contain one nested lopping structure that’s similar to function shuffle.

Code in C language.

#include

#include

#include

#define SUITS 4

#define FACES 13

#define CARDS 52

//prototypes

void shuffle(unsigned int wDeck[][FACES]); //shufling modifies wDeck

void deal(unsigned int wDeck[][FACES], const char *wFace[], const char *wSuit[]); //dealing doesn't modify arrays

int main()

{

//initialize suit array

const char *suit[SUITS] = {"Hearts", "Diamonds", "Clubs", "Spades"};

//initialize face array

const char *face[FACES] = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};

//initialize deck array

unsigned int deck[SUITS][FACES] = {0};

srand(time(NULL)); //seed random-number generator

shuffle(deck);

deal(deck, face, suit);

}

void shuffle(unsigned int wDeck[][FACES])

{

size_t row; //row #

size_t column; //column #

size_t card; //counter

//for each of the cards, choose slot of deck randomly

for (card = 1; card <= CARDS; ++card)

{

//choose new random location until unoccupied slot found

do

{

row = rand() % SUITS;

column = rand() % FACES;

} while(wDeck[row][column] != 0);

//place card # in chosen slot of deck

wDeck[row][column] = card;

}

}

//deal cards in deck

void deal(unsigned int wDeck[][FACES], const char *wFace[], const char *wSuit[])

{

size_t card; //card counter

size_t row; //row counter

size_t column; //column counter

//deal each of the cards

for(card = 1; card <= CARDS; ++card)

{

for(row = 0; row < SUITS; ++row)

{

for(column = 0; column < FACES; ++column)

{

//if slot contains current card, display card

if (wDeck[row][column] == card)

{

printf("%5s of %-8s ", wFace[column], wSuit[row], card % 2 == 0 ? ' ' : ' ');

}

}

}

}

}

Explanation / Answer

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define SUITS 4
#define FACES 13
#define CARDS 52

//Prototype of the function
//Dealing doesn't modify arrays because the parameters of type pointer
void deal(unsigned int wDeck[][FACES], const char *wFace[], const char *wSuit[]);
//Main method definition
int main()
{
//Initialize suit array
const char *suit[SUITS] = {"Hearts", "Diamonds", "Clubs", "Spades"};

//Initialize face array
const char *face[FACES] = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};

//Initialize deck array
unsigned int deck[SUITS][FACES] = {0};

//Seed random-number generator
srand(time(NULL));

//Calls the method to shuffle and deal operation
deal(deck, face, suit);
}

//Function to Shuffle and Deal cards in deck
void deal(unsigned int wDeck[][FACES], const char *wFace[], const char *wSuit[])
{
//Counter for Card
size_t card;
//Counter for Row
size_t row;
//Counter for column
size_t column;

//Shuffle operation
//For each of the cards, choose slot of deck randomly
for (card = 1; card <= CARDS; ++card)
{
//Choose new random location until unoccupied slot found
do
{
//Generates a random number for row
row = rand() % SUITS;
//Generates a random number for column
column = rand() % FACES;
} while(wDeck[row][column] != 0); //End of do-while loop

//Place card # in chosen slot of deck
wDeck[row][column] = card;
}//End of for loop

//Deal operation
//Deal each of the cards
for(card = 1; card <= CARDS; ++card)
{
//Loops 4 times for suits
for(row = 0; row < SUITS; ++row)
{
//Loops 12 times for faces
for(column = 0; column < FACES; ++column)
{
//If slot contains current card then display the card
if (wDeck[row][column] == card)
{
printf("%5s of %-8s ", wFace[column], wSuit[row], card % 2 == 0 ? ' ' : ' ');
}//End of if condition
}//End of inner loop for faces
}//End of inner loop for suits
}//End of outer loop for cards
}//End of method
