Question

• Write a struct to represent a playing card. Playing cards have the following features:

They have a suit. This suit can be one of the following: clubs, diamonds, hearts, spades
They have a rank. Valid ranks are any number between 2 and 10 (inclusive of 2 and 10), plus ace, jack, queen, and king.

Define two enums (Suit and Rank) to represent suits and ranks.

• Write a short main function to generate a random card, and then print the card's rank and suit. Use the rand() function from the library stdlib.h

NOTE ON rand(): Before calling rand(), you must seed the random number generator.

NOTE ON rand(): rand() generates a random integer between 0 and RAND_MAX, which is a much larger number than you'll be using to generate your random cards. To get the number down to an appropriate range, use the % operator on the result from rand()

NOTE ON rand(): rand() is not the best source of randomness -- you may find it yielding predictable results, even if you correctly seed the random number generator

//C++ program

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

enum suit{HEARTS,CLUBS,SPADES,DIAMONDS};
enum rank{Ace=1,_2,_3,_4,_5,_6,_7,_8,_9,_10,Jack,Queen,King};

struct card{
   suit s;
   rank r;
};

void print_rank(int r){
   switch(r) {
case Ace: cout << "Ace"; break;
case Jack: cout << "Jack"; break;
case Queen: cout << "Queen"; break;
case King: cout << "King"; break;
default: cout << r; break;
}
}

void print_suit(int suit)
{
switch(suit) {
case HEARTS: cout << "HEARTS"; break;
case CLUBS: cout << "CLUBS"; break;
case SPADES: cout << "SPADES"; break;
case DIAMONDS: cout << "DIAMONDS"; break;
}
}

int randomNumber(int min , int max){
   return min + rand()%(max-min+1);
}

void generateRandomCard(){
   int cardNumber = randomNumber(1,52);
   struct card c;
   c.s = suit(cardNumber % 4);
   c.r = rank(cardNumber% 13 + 1);
  
   cout<<"Your card is : ";
   print_suit(c.s);
   cout<<" ";
   print_rank(c.r);
}

int main()
{
srand(time(NULL));
generateRandomCard();
return 0;
  
}
