Hi, I am writing a card playing program as a way of learning C#.
I ran into an issue with an array going out of bounds.
Here is my code:
namespace Pcardconsole
{
class Deck
{
public Deck()
{
// Assign standard deck to new deck object
int j;
for (int i = 0; i != CurrentDeck.Length; i++)
{
CurrentDeck[i] = originalCards[i];
}
// Fisher-Yates Shuffling Algorithim
Random rnd = new Random();
for (int k = CurrentDeck.Length - 1; k >= 0; k++)
{
int r = rnd.Next(0, k + 1);
int tmp = CurrentDeck[k];
CurrentDeck[k] = CurrentDeck[r];
CurrentDeck[r] = tmp;
// Console.WriteLine(i);
}
}
public void Shuffle()
{
// TODO
}
// public int[] ReturnCards()
// {
// TODO
// }
public int[] originalCards = new int[54]
{
0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D,
0x21, 0x22, 0x23, 0x24, 0x25, 0x26, 0x27, 0x28, 0x29, 0x2A, 0x2B, 0x2C, 0x2D,
0x31, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, 0x3A, 0x3B, 0x3C, 0x3D,
0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4A, 0x4B, 0x4C, 0x4D,
0x50, 0x51
};
public int[] CurrentDeck = new int[54];
}
class Program
{
static void Main(string[] args)
{
// Create a Deck object
Deck mainDeck = new Deck();
Console.WriteLine("Here is the card array:");
for (int index = 0; index != mainDeck.CurrentDeck.Length; index++)
{
string card = mainDeck.CurrentDeck[index].ToString("x");
Console.WriteLine("0x" + card);
}
}
}
The hexidecimal numbers stand for different cards.
When I compile it I get an array index out of bounds error, and a crash.
I don't understand what is wrong.
Any help would be much appreciated.
