Title: Homework Help c#
Post by: reaper2191 on January 19, 2014, 08:23:24 AM

Okay, so I havent taken c# in over a year and a half and im really no good at it. Im not really looking for a solution just ideas and some syntax error help.
Heres what I am trying to do:
Write a C# program to simulate the drawing from a deck of 52 porker cards valued from 1 to 13 with 4 suits.  One round of drawing consists of randomly pull any 4 cards from the 52-card deck. Therefore, the same card cannot appeared more than once.  The program will perform 10,000 rounds of drawing and tallying the frequencies of the following possible results for the 4 cards pulled: (a)the 4 cards are having the same suit, (b)the 4 cards are from the 4 different suits, (c)the 4 cards are having the same value, (d)3 cards have the same value, (e)exactly 2 different pairs of 2 same-value cards, and (f)only 2 cards have the same value. Notice that (b) may occured together with (c) - (f).

This is what I have so far:
using System;

namespace ConsoleApplication3
{

    class Program
    {
        int[] ranArr = new int[4];

        static int GenerateRandomNum()
        {
            int cleanRandNum;
            Random ran = new Random();
            cleanRandNum = ran.Next(1, 53);

            return cleanRandNum;
        }
        static void Main(string[] args)
        {



            int[] crdv = new int[4]; //1-13

            int[] crds = new int[4];//1-4


            int idx, randNum;

            //Draw 4 cards

            for (idx = 0; idx < crdv.Length; idx++)
            {
                //randNum = ran.Next(1, 53);



                Console.Write(randNum + ", "); //Getting a syntax error for this int randNum and the one below. Use of unassigned local variable 'randNum'

                crdv[idx] = randNum % 13; //Remander value     Heart = 1, Spades = 2, Diamonds = 3, Clubs = 4
                if (crdv[idx] != 0)
                    crds[idx] = randNum / 13 + 1;
                else crds[idx] = randNum / 13;
                if (crdv[idx] == 0) crdv[idx] = 13;
               
                //crdv[idx] = ran.Next(1, 13);//Card values Ace-King
                //crds[idx] = ran.Next(1, 5);//Card Suits (H,C,S,D)

            }

            // Array.Sort(crdv);//Sorts values

            // Array.Sort(crds);//Sorts Suits

            foreach (int val in crdv)
                Console.Write(val + ", ");

            Console.WriteLine();



            foreach (int suit in crds)
                Console.Write(suit + ", "); //Spade=1,Hearts=2,Clubs=3,Diamonds=4

            Console.Read();

        }

    }

}

From some lessons I took online at the MS C# academy, they say to try to read it like a paragraph. The thing is that Im not really understanding what I am doing lol. The program above is the assignment we have been working on in class. I just need to know I am heading in the right direction and if not where to fix it and how. The commented out section is what we started with before adding other stuff in. I just commented those out so I wouldnt lose them since the program ran with them.

Thanks for any and all help!
