poker sorting

Modify the following code, write a hand-sorting routine. In card game, most players keep their cards sorted by pip value. The routine places ace first, kings next, and to forth, down to tows. A hand is five cards.

public class Card
{
public enum Suit { clubs, diamonds, hearts, spades }
public class Pips
{ // inner class
public void SetPips(int n) { p = n % 13 + 1; }
public int GetPips() { return p; }
private int p; // values 1 to 13
}
public void SetCard(int n)
{ s = (Suit)(n/13); p = new Pips(); p.SetPips(n); }
public Suit GetSuit() { return s; }
public Pips GetPips() { return p; }
private Suit s;
private Pips p;
}// end of Class Card
public class Deck
{
public void SetDeck()
{
d = new Card[52];
for (int i = 0; i < 52; ++i)
{
d[i] = new Card();
d[i].SetCard(i);
}
}
public void Shuffle()
{
Random t = new Random();
for (int i = 0; i < 52; ++i)
{
int k = i + (t.Next() % (52 - i));
Card cTemp = d[i]; // swap cards
d[i] = d[k];
d[k] = cTemp;
}
}
public void Deal(int n, int pos, Card[] hand)
{
for (int i = pos; i < pos + n; ++i)
hand[i - pos] = d[i];
}
private Card[] d;
}
class Flush
{
public static void Main()
{
Card[] oneHand = new Card[7];
Deck dk = new Deck();
int i, j, k, flushCount = 0;
int [] sval= new int[4];
int ndeal= 1000, nc = 7, nhand = 52/nc;
dk.SetDeck();
for (k = 0; k < ndeal; k += nhand)
{
if ((nhand + k) > ndeal)
nhand = ndeal - k;
dk.Shuffle();
for (i = 0; i < nc * nhand; i += nc)
{
for (j = 0; j < 4; ++j)
sval[j] = 0;
dk.Deal(nc, i, oneHand); // deal next hand
for (j = 0; j < nc; ++j)
sval[(int)oneHand[j].GetSuit()]++;
for (j = 0; j < 4; ++j)
if (sval[j] >= 5) // 5 or more is flush
flushCount++;
}
}
Console.WriteLine("In " + ndeal + " " + nc + "-card hands there were " + flushCount + " flushes");
}
}

Ok... are you giving away your code or to you have a question about it?

I need somebody to help me to rewrite the code that I post

yui0329,

I don't know if your teacher let you use other interfaces,I didn't find the meaning of some words in your post in my english dictionary!

anyway when I want to do such things..I do like below,

Code:

    public enum Sort { Name, Average, Age, ID }
    public class Student:IComparable
    {
        string m_name=string.Empty;
        int m_average=0;
        int m_age=0;
        int m_id=0;
        public Student(string name,int age,int average,int ID)
        {
            m_name=name;
            m_average=average;
            m_age=age;
            m_id=ID;
        }
        #region IComparable Members

        public int CompareTo(object obj)
        {
            return m_id.CompareTo(((Student)obj).m_id);
        }

        #endregion
        class comparer:IComparer
        {
            Sort m_sort;
            public comparer(Sort sort)
            {
                m_sort=sort;
            }
            #region IComparer Members

            public int Compare(object x, object y)
            {
                Student studentx=(Student)x;
                Student studenty=(Student)y;
                switch(m_sort)
                {
                    case Sort.Age:
                        return studentx.m_age.CompareTo(studenty.m_age);
                    case Sort.Average:
                        return studentx.m_average.CompareTo(studenty.m_average);
                    case Sort.ID:
                        return studentx.m_id.CompareTo(studenty.m_id);
                    case Sort.Name:
                        return studentx.m_name.CompareTo(studenty.m_name);
                }
                return studentx.m_id.CompareTo(studenty.m_id);
            }

            #endregion
        }
        public static IComparer SortStudents(Sort sort)
        {
            return new Student.comparer(sort);
        }
        public override string ToString()
        {
            return string.Format("name is {0},age is {1},average is {2},ID is {3}",
                m_name,m_age.ToString(),m_average.ToString(),m_id.ToString());
        }

    }

to use

Code:

        private void ToUse()

Code:

        {
            Student student1=new Student("mehdi",21,0,1);
            Student student2=new Student("reza",21,10,2);
            Student student3=new Student("armin",17,12,3);
            ArrayList students=new ArrayList();
            students.Add(student1);
            students.Add(student2);
            students.Add(student3);
            IComparer comparer=Student.SortStudents(Sort.Age);
            students.Sort(comparer);
            string result=string.Empty;
            foreach(Student student in students)
                result+=student.ToString()+"%%";
            textBox1.Text=result;
        }

you see I used some built-in interfaces.it doesn't solve your problem just shows you a way.I hope you get its scenario..
