Trouble with card game functions

[Kohlerbear]

I am currently writing a go fish program and am having some trouble manipulating my functions. For general context, here are my current functions:

void shuffle(int ocean[]){//working 
int hold=0;
int i=0;
int n;
while ( i <31){
	n= 1 + rand() % 32;
	ocean[hold] = ocean[i];
	ocean[i] = ocean[n];
	ocean[n] = ocean[hold];
	i=i+1;
	}
}



int drawCard (int ocean[], int hand[], int& deckPos, int& handPos)
{
hand[handPos]=ocean[deckPos];
deckPos=deckPos + 1;
handPos = handPos + 1;
return deckPos;
return handPos;

}


void pairCount (int hand1[], int hand1Pos){
int count[11]={0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; //enough room to count all the occurences from 2 to 9
int temp;
for (int i=0; i<hand1Pos; i++){
	temp=hand1[i];
	count[temp]++;
	}
int x=2;
while (x<9){
if (count[x]==4){
	cout << "Game Over! Four occurences of " << x << " have occured " << endl;
	x=10;}//ends loop because a winner was found 
else {
	x++;}// if no winner is found at count[x], increment the counter 
}
}


int cardCheck (int guess, int hand1[], int& hand1Pos, int hand2[], int& hand2Pos, int ocean[], int& deckPos){


for (int i=0; i<hand2Pos; i++){//checking computer's hand for player's guess
if (hand2[i]==guess){
cout << "I do. I have one " << endl; //still need to figure out how to x occurences (not just one) 
hand1Pos++; //if the guess is in the opponent's hand, increment player's hand to prepare for the card to be added
hand1[hand1Pos-1]=guess; //add the guess to player's hand
hand2[i]=hand2[hand2Pos-1];
hand2Pos--;
return hand1Pos, hand2Pos, deckPos;
}
}

	
cout << "Go fish!" << endl;
drawCard(ocean, hand1, deckPos, hand1Pos);
return hand1Pos, hand2Pos, deckPos;

}

This game is to be played with a deck of 32 with cards from 2 to 9. If the player or the computer gets 4 of the same number, the game is over. Currently, my main concern resides with my cardCheck function, it works for single occurrences, however, I am not sure how to return how many occurrences of a given card. (For example, if I input guess to be 7, I want the computer to reply "I do. I have " x " amount of sevens.) Could somebody please point me in the right direction? If anything is unclear or you need to see the rest of my code please ask. Thanks.
