C programming, Poker game...
I'm having trouble with a poker game. I was able to print out the correct hand (straight, three of a kind, etc.) for one player after they input their own cards.... but now I need to add a second player and i need their hands to compare and figure out who the winner is. And i just dont know where to start. There are no suits when you are playing the game so please ignore any part of the code that has to do with suits.
Also, if there is a way to input the players' cards into an array for each player and work the program like that i'd greatly appreciate it if anyone could help me out with that as well.
Code:
/* Classifies a poker hand */
#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>
#define NUM_RANKS 13
#define NUM_SUITS 4
#define NUM_CARDS 5
/* external variables */
int num_in_rank[NUM_RANKS];
int num_in_suit[NUM_SUITS];
bool straight, flush, four, three;
int pairs; /* can be 0, 1, or 2 */
/* prototypes */
