Explanation / Answer

// save as deck.c
// if u face any error. please let me know.

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

void initDeck(DeckT *deck)
{
int i;
deck->count = 0;
for(i=0; i<DECK_SIZE; i++)
{
initCard(deck->cards[i],i);
}
}

void shuffleDeck(DeckT *deck)
{
int i;
int j;
printf("Printing deck values before shuffling ");
for(i=0; i<52; i++)
printf("%d ",deck->cards[i].value);
printf(" ");
srand(time(NULL));
for(i=51; i>=0; i--)
{
j = rand()%(i+1);
int temp = deck->cards[j].value;
deck->cards[j].value = deck->cards[i].value;
deck->cards[i].value = temp;
}
printf("Printing deck values After shuffling ");
for(i=0; i<52; i++)
printf("%d ",deck->cards[i].value);
}

CardT dealOneFromDeck(DeckT *deck)
{
int value = rand()%52;
return deck->cards[value];
}

void displayDeck(const DeckT *deck)
{
int i;
for(i=0; i<DECK_SIZE; i++)
displayCard(deck->cards[index]);
}
