Can anyone help with arrays

Shaker AlSalem

Can anyone please help me write this in a console app

Thank you so much for your time and support.
The game of Craps consists on rolling a pair of dice as many times as possible until you either win or lose. The rules are as follows:
- If in the first roll you get a 7 or 11, you win in the first throw
- If in the first roll you get a 2, 3 or 12, you lose in the first throw
- If you get any other value, that value becomes the "point". Then you keep throwing the dice until you either get the "point" to win or a 7 to lose.
These are the basics of the game, side bets are a different topic.
Simulate the playing game of Craps 10000 times. And make your code answer the following questions:
- How many times you got to WIN / LOSE
- How Many times you won/lost in the first roll
- How Many times you won/lost in the 2nd, 3rd, 4th.........10th roll and more than 10 rolls.
You should have a method named PlayCraps that plays one single game of craps that will allow you to find out if you win or loose and the length of the game in the number of throws. You will get to design how will that be accomplished.

int PlayCraps (ref bool isWin)

- return the number of times the dice were thrown
int n = 0;
bool isWin = true;
n = PlayCraps(ref isWin);
if (isWin)
{
//for a win
}
else
{
///for a loss
}

Well, shall we say that it needs some work :)

I've moved it on a bit by coding the PlayCraps method and calling it just a single time from the Main() method.

What you need to do now is to change the code in the Main() method to call it 10000 times, count and display the results:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication2
{
public class Booleans
{
static Random rand = new Random();

static void Main()
{
int n = 0;
bool isWin = true;
n = PlayCraps(ref isWin);

if (isWin)
{
Console.WriteLine("You won in {0} rolls(s)", n);
}
else
{
Console.WriteLine("You lost in {0} roll(s)", n);
}

Console.ReadKey();
}

static int PlayCraps (ref bool isWin)
{
int throw1 = rand.Next(1,7);
int throw2 = rand.Next(1,7);
int score = throw1 + throw2;

if (score == 7 || score == 11)
{
isWin = true;
return 1;
}

if (score == 2 || score == 3 || score == 12)
{
isWin = false;
return 1;
}

int point = score;
int n = 1; // number of times dice thrown

while(true) // infinite loop
{
n++;
throw1 = rand.Next(1,7);
throw2 = rand.Next(1,7);
score = throw1 + throw2;

if (score == point)
{
isWin = true;
break;
}

if (score == 7)
{
isWin = false;
break;
}
}

return n;
}

}
}

OK, this is not yet done, but i need to know if im going on the right track, I'm kind of crapy with c# myself. Thanks!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication2
{
public class Booleans
{
static Random rand = new Random();

int PlayCraps (ref bool isWin);

}

return 10000
int n = 0;
bool isWin = true;
n = PlayCraps(ref isWin);
if (isWin)
{
int throw = rand.Next(1,7)
int throw = rand.Next(5,7)
int throw = rand.Next(6,6)
//for a win
}
else
{
int throw = rand.Next(1,2)//2
int throw = rand.Next(1,3)
int throw = rand.Next(2,2)//3
int throw = rand.Next(6,7)//12
///for a loss
}
}

I'll give you a hint to help you get started.

To simulate the throwing of two dice you need to generate two random numbers between one and six. You can do this using the System.Random class:

static Random rand = new Random(); // it's usually best to store this in a static field

// ...

int throw = rand.Next(1, 7); // endpoint needs to be one more than the actual number needed
