Question

Please write in C Programming

Your task is to "deal" a card from the card deck. standard 52 deck

/* Function: dealCard()

Purpose: Pick a card at random from the deck

Accepts: struct Card * -- pointer to array of cards (deck)

Returns: struct Card * -- pointer to the dealt card*/

struct Card *dealCard(struct Card *deck) {

// Iterate through the entire deck to make sure there is at least one card that has NOT been dealt

// If all cards are dealt, return a 0

// Generate a random number to pick a card randomly from the deck

// If the card is not available (has been dealt), then try another random number (loop until you get an available card)

// set the card as "dealt" and return it

}

Answer 1

#include<stdio.h> //for printf and scanf
#include<stdlib.h> //for srand function
#include<time.h> //for time function
#include<stdbool.h> //for bool datatype
//struct card with attributes ch represents card number and dealt to know card status
struct card{
int ch;
bool dealt;
};

//returns 0 if all cards are taken, else returns the randomly generated card
struct card *dealCard(struct card *deck)
{
int i;
srand(time(0)); //for generating distinct numbers
for(i=0;i<52;i++){
if(deck[i].dealt==false)
break;
}
if(i==52)
return 0;
while(1){
i = rand()%52;
if(deck[i].dealt==false){
deck[i].dealt=true;
break;
}
}
return (deck+i);
}

//main function implementation
int main()
{
struct card deck[52],*ptr;
int i;
for(i=0;i<52;i++){ //sets the intial values for deck
deck[i].ch=i+1;
deck[i].dealt=false;
}

//calls the function for 11 times and prints the returned card number
for(i=0;i<=10;i++){
ptr=dealCard(deck);
printf("Card %d\n",ptr->ch);
}
return 0;
}
