Can't figure this out

EDIT: All I did was take out ", pairarr[2]={0}, twopairarr[4]={0}" from the declaration line and it worked. Please explain why it messed up my program? Thanks

Hey guys, I created this program for my class, and most of it is working and I've been fixing it a lot but new problems seem to come up.

This program is a basic poker game, which shuffles the deck and displays a 5 card hand, then tells the user what kind of hand they have (pair, three of a kind, flush, etc)

For some reason, whenever I have an Ace in the hand, it seems to mess it up, here's a couple examples:

Six of ---
King of ---
Ace of ---
Eight of ---
Three of ---
and it will show that there is a pair...

Queen of ---
Deuce of ---
Eight of ---
Ace of ---
Deuce of ---
and it will show that there is two pairs

Thanks in advance for helping
My guess would be to first look at how I check for pairs, three of a kind, etc. The problem won't be anywhere else than the main I think, I'm positive it has something to do with how I check for hand types, I will keep looking over it also.

Here is my code:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void shuffle(int [][13]);
void deal(int [][13], char *[], char*[], int[][2]);
void hand(int [][13], char *[], char*[]);
void pair(int [][2]);
void bubblesort(int [][2]);

void main()
{
    int cards[5][2] = {0};//hand
    int i, k, j, x=0, z, y, f;//counters
    int fullhouse=0, straight=0, flush=0, fourkind=0, threekind=0, twokind=0, pair=0, pairarr[2]={0}, twopairarr[4]={0};
    char *suit[4] = {"Hearts", "Diamonds", "Clubs", "Spades"};
    char *face[13] = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
    int deck[4][13] = {0};
 
    srand(time(0));
 
    shuffle(deck);
    deal(deck, face, suit, cards);
   
   for(x=0; x<=4; x++)
        puts("");
 
   for(i = 0; i < 5; i++)
   {
        printf("%-8sof  %8s\n", face[cards[i][0]],suit[cards[i][1]]);//prints hand
   }
 
   bubblesort(cards);
  
   /////pair/////
   for(j=1; j<5; j++)

                twokind += 1;
           if(twokind == 1)
        		pair = 1;    
       }
