C++ Poker Simulation

[bluewhale628]

Hello everyone! I am currently working on creating a Poker Simulation using the language C++. However, I am having issues with my swap function and also creating the conditions, such as declaring a Flush or Pair. Here is the code I have so far, and if you can assist me with that that would be great.

#include <iomanip>
#include <iostream>
using namespace std;
void getCard(int);
void shuffle(int[]);
void swapHand(int[]);
int position = 0;
int deck[52];

int main()

{
	srand( unsigned(time(0)));
	int hand[5];
	int cardNumber;
	char arr[100];

	shuffle(deck);

	for(int i=0; i<52; i++)
		getCard(deck[i]);

	for(int i=0; i<5; i++)
	{
		hand[i] = deck[position++];
	}

	cout << "\n" << "Welcome to Kim's WissPoker!" << "\n" << endl;
	cout << "YOUR HAND:" << endl;
	for(int i=0; i<5; i++)
		getCard(hand[i]);

	cout << "\n"<< "Which card(s) would you like to reject? (1-5)" << endl;
	cin >> hand[cardNumber];
	swapHand([cardNumber]);

	bool running = true;
	while (running)
	{
	cout << "Would you like to reject another card? (Y or N)" << endl;
	cin.getline(arr,100);
	if (arr[0] == 'n' || arr[0]=='N')
			running = false;
	}

	
cout << "\n";	
system ("pause");
return 0;
}

void shuffle(int arr[])
{
	int range = 52;
	int startingPoint = 0;
	arr[0] = ( rand() % range ) + startingPoint;
	for(int i = 1; i < 52; i++)
	{
		arr[i] = ( rand () % range ) + startingPoint;
		for(int shuffle = i-1; shuffle >= 0; shuffle--)
		{
			if(arr[i] == arr[shuffle])
				i--;
		}
	}
}

void getCard(int randNum) {
	switch(randNum)
    {
        case 1:
            cout << "2 of Clubs" << endl;
        break;

}

void swapHand(int hand[])
{
	for(int i = 0; i <= 5; i++)
	{
		getCard(deck[i]);
		hand[i] = deck[position++];
	}
}

Note, the formatting may turn out distorted.

check line 35. Syntax error.
Also, I doubt int cardNumber is not initialized anywhere.

Here's a rough schema that might work to evaluate a hand given your format.

Cards with number 1-13 are clubs, 14-26 are diamonds, etc. So if all cardsnumbers are within 1-13 you have a flush in clubs, 1-26 you have a flush in spades, etc. If all cardnumbers are within a given suit range and are also consecutive, then you have a straight flush and if all cards are within the given suit range, consecutive and the lowest value is 9 or 9 + x*13 then you have a royal flush in the given suit.

A pair would be if any two given cardnumbers differed by multiple of 13 (cardnumbers 1 and 14 would be a pair of twos. Three of a kind and 4 of a kind could be evaluated similarly.

A full house could also be found if you look for both a pair and 3 of a kind in the same hand.

Straights that aren't also flushes are going to be a bit more of a hassle with your format. I guess I'd try to convert the cardnumber of each card in the hand to a number between 1 and 13 inclusive by subtracting 13 from the given cardnumber until the value of the remainder is less than 14. Then I'd sort the numbers and see if the numbers are consecutive. If so, its a straight.
