Thread: Function Pauses

I have a function which shuffles a deck of cards the problem is when the function is called again it sits there and does nothing

Code:

void shuffleDeck(int wDeck[4][13])
{
	
	int card, row, column;
	
	/* Randomize */
	srand(time(NULL));
	
	for (card=1;card<=52;card++)
	{
		row = rand() % 4;
		column = rand() % 13;
		
		while (wDeck[row][column] != 0)
		{
			row = rand() % 4;
			column = rand() % 13;
		}
		
		wDeck[row][column] = card;
	}
	
}

I have no idea why it does that. This pauses even when its in a smaller app just to debug the function so its not the I am using in my program that uses it.

Ok I took it out and put it in the main function however I dont think srand() is the problem, as its still pausing.

Ok I did some debugging with checking where the program was stopping. I found that the while () loop was the cause as it was finding 0 as it wasnt defined to 0 I made another function which goes through the deck and makes them 0

Code:

void deleteDeck(int wDeck[4][13])
{
	
	int row, column;
	
	for (row=0;row<4;row++)
		for (column=0;column<13;column++)
			wDeck[row][column] = 0;
	
}

Thanks totally forgot about memset
