Is it possible to create a simple text card game using C programming?

Hi Everyone, I want to create a simple card game similar to 'war' that battles the user and the 'computer'. I was thinking there could be one round where the cards are shuffled and given to each player, players cards are then evaluated and the winner is chosen for that round.

Whats the best way to do this? Can someone give me an example?

Thanks

Sure, post your latest code.
But make sure you use "copy as text" in your IDE and/or "paste as text" in your browser, to stop it looking a mess (as you deleted from your other posts).

Hi! i'm so sorry I deleted the content, I have no idea what I'm doing on this site, but I'm beginning to get used to it. I decided to make a card game that assigns each player 5 cards, but I have a issue- each time the game is played the players receive the same cards. How can I fix this? I appreciate all the help. I've been working on this for hours and can't figure it out.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>
//constants declared
#define NUMOFCARDS 52
#define NUMOFPROPERTIES 2
#define NUMOFSUITS 4
#define NUMOFFACES 13
#define PLAYERCARDS 2
//declaration of arrays
char *suit[NUMOFSUITS] = { "Hearts", "Spades", "Clubs", "Diamonds" };

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

//calling functions
void PrintCard(int deck[NUMOFCARDS][NUMOFPROPERTIES], int i);
void InitDeck(int deck[NUMOFCARDS][NUMOFPROPERTIES]);
void SwapCards(int deck[NUMOFCARDS][NUMOFPROPERTIES], int src, int dest);
void ShuffleDeck(int deck[NUMOFCARDS][NUMOFPROPERTIES]);
int main()
{
  //declaration of varaiables

  int player1Deck[5];
  int src = 0;

    printf("Player %d\n", players + 1);
    for (i = 0; i < PLAYERCARDS; i++) {
      PrintCard(deck, i);
    }
    printf("\n");
  }
  return 0;
}

void InitDeck(int deck[NUMOFCARDS][NUMOFPROPERTIES])
{
  int suit;
  int face;
  int row = 0;
  for (suit = 0; suit < 4; suit++)
    for (face = 0; face < 13; face++) {
      deck[row][0] = suit;
      deck[row][1] = face;
      row++;
    }
}

void ShuffleDeck(int deck[NUMOFCARDS][NUMOFPROPERTIES])
{
  int src, dest, i;
  srand(time(NULL));
  for (i = 0; i < NUMOFCARDS; i++) {
    src = i;
    dest = rand() % NUMOFCARDS;
    SwapCards(deck, src, dest);
  }
}

void SwapCards(int deck[NUMOFCARDS][NUMOFPROPERTIES], int src, int dest)
{
  int temp;
  temp = deck[src][0];
  deck[src][0] = deck[dest][0];
  deck[dest][0] = temp;
  temp = deck[src][1];
  deck[src][1] = deck[dest][1];
  deck[dest][1] = temp;
}

void PrintCard(int deck[NUMOFCARDS][NUMOFPROPERTIES], int i)
{
  int tempsuit;
  int tempface;
  tempsuit = deck[0];
  tempface = deck[1];
  printf("Card %d = %s of %s\n", i + 1, face[tempface], suit[tempsuit]);
}

Your PrintCard is broken.

Code:

---

$ gcc bar.c
bar.c: In function ‘PrintCard’:
bar.c:90:12: warning: assignment makes integer from pointer without a cast [-Wint-conversion]
  tempsuit = deck[0];
            ^
bar.c:91:12: warning: assignment makes integer from pointer without a cast [-Wint-conversion]
  tempface = deck[1];
            ^

deck is a 2D array, so you need two subscripts.

Calling srand() in ShuffleDeck is redundant. You're already calling srand() in the best place possible (at the start of main).
Calling it more than once won't make rand() any better. Calling it too often will make rand() much worse.

Aside from that, it works for me.

Code:

---

$ ./a.out
Please enter the number of players (1-3):
1
Player 1
Card 1 = Four of Spades
Card 2 = Jack of Clubs

$ ./a.out
Please enter the number of players (1-3):
1
Player 1
Card 1 = Jack of Hearts
Card 2 = King of Spades

$ ./a.out
Please enter the number of players (1-3):
1
Player 1
Card 1 = Five of Spades
Card 2 = Seven of Hearts
