Thread: Snap Card Game

This is bunch of code i have for my Snap Game the problem that i face was it only comparing one deck only. May help me on how I can make it to comparing each card from both deck?

Code:

 #include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <stdbool.h> // #include the std boolean library

#define CARDS 52
#define DRAW 104

//The program will first open Deck 1 then Deck 2, after Deck 2 it will open Deck 1 back and repeat.
bool Deck1 = true;
bool Deck2 = false;

//The program contains two Decks
int deck1[CARDS];
int deck2[CARDS];
int UserSelection, a, b, c, d;
char *suit[4] = { "Spades", "Hearts", "Clubs", "Diamonds" }; // Pattern of card

void showcard(int card);
void DisplayDeck();
void MainMenu();

int main()
{
    MainMenu();

    return 0;
}

void DisplayDeck()
{
    for (int a = 0; a < CARDS; a++) //initialize the first deck, to check whether the number has been taken
        deck1[a] = 0;
    for (int c = 0; c < CARDS; c++) //second deck
        deck2[c] = 0;


    while (1) // infinite loop
    {
        // when the deck one is open, deck two is close see the card in deck one
        //if (Deck1 == true && Deck2 == false)
        {
            srand((unsigned)time(NULL)); //first deck
            for (int a = 0; a < DRAW; a++)
            {
                for (;;)//infinite loop
                {
                    b = rand() % 52;
                    if (deck1[b] == 0)
                    {
                        deck1[b] = 1;

                        showcard(b);
                        break;
                    }
                }

            }

        }
        // when the deck two is open, deck one is close see the card in deck one
        //else if (Deck2 == true && Deck1 == false)
        {
        srand((unsigned)time(NULL));
        for (int c = 0; c < DRAW; c++) //second deck
        {
            for (;;)
            {
                d = rand() % 52;
                if (deck2[d] == 0)
                {
                    deck2[d] = 1;

                    showcard(d);
                    break;
                }

> if (deck1 == deck2)
This doesn't compare each element of both arrays.

If they were two arrays of char, each with a \0, then you would write
if ( strcmp(deck1,deck2) == 0 )

But these are two arrays of int, so you need to hand-roll your own for loop to compare each deck1[i] and deck2[i] for equality.
