War Card Game in GUI

OK, try this.

You'll need to add a read-only multiline textbox (txtResult say) under your buttons (btnDeal and btnPlay say) which is big enough to display 9 lines of text. The skeleton handlers for all events should, of course, be added via the VS designer rather than manually so they are wired up automatically to the events:

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

int[] deck = new int[52]; // all zero by default

int lastCardIndex = 0;

string[] cards = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King" };

string[] suits = { "clubs", "diamonds", "hearts", "spades" };

Random rand = new Random();

int totalComputer = 0; // records total points for computer

int totalPlayer = 0; // ditto for player

int show = 0;

public Form1()

{

InitializeComponent();

}

private void btnDeal_Click(object sender, EventArgs e)

{

txtResult.Clear();

Array.Clear(deck, 0, 52);

for (int i = 0; i < 52; i++)

{

while (true)

{

int num = rand.Next(1, 53); // get number between 1 and 52 inclusive

if (Array.IndexOf(deck, num) == -1) // not already used

{

deck[i] = num;

break;

}

btnDeal.Enabled = false;

btnPlay.Enabled = true;

}

private void btnPlay_Click(object sender, EventArgs e)

{

string score;

string result;

if (show == 26)

{

if (totalComputer > totalPlayer)

score = "Computer wins!";

else if (totalComputer < totalPlayer)

score = "Player wins!";

else

score = "It's a draw!";

result = "";

result += String.Format("Final result\r\n\r\n");

result += String.Format(" Computer Score is {0}\r\n", totalComputer);

result += String.Format(" Player Score is {0}\r\n\r\n", totalPlayer);

result += score;

result += "\r\n\r\nPress Deal button to start another game";

txtResult.Text = result;

lastCardIndex = 0;

totalComputer = 0;

totalPlayer = 0;

show = 0;

btnDeal.Enabled = true;

btnPlay.Enabled = false;

btnDeal.Focus();

return;

}

string computerSuit;

int computer = SelectCard(out computerSuit) - 1;

string playerSuit;

int player = SelectCard(out playerSuit) - 1;

if (computer > player)

{

totalComputer += 2;

score = "Computer gets 2 points";

}

else if (computer < player)

{

totalPlayer += 2;

score = "Player gets 2 points";

}

else

{

totalComputer += 1;

totalPlayer += 1;

score = "1 point each";

}

result = "";

result += String.Format("Show # {0}\r\n\r\n", show + 1);

result += String.Format(" Computer has {0} of {1}\r\n", cards[computer], computerSuit);

result += String.Format(" Player has {0} of {1}\r\n\r\n", cards[player], playerSuit);

result += score;

show++;

if (show == 26)

{

result += "\r\n\r\nGame over - press Play button to display final result!";

}

txtResult.Text = result;

}

int SelectCard(out string suit)

{

int num = deck[lastCardIndex];

lastCardIndex++;

suit = suits[(num - 1) % 4];

return (num - 1) / 4 + 1;

}

private void Form1_Load(object sender, EventArgs e)

{

btnPlay.Enabled = false;

}
