programming part-2 ?

Easy after you've done the first part.

Try:

using System;

class School : IComparable

{

private string _name;

private int _enrolment;

public string Name

{

get { return _name; }

set { _name = value; }

}

public int Enrolment

{

get { return _enrolment; }

set { _enrolment = value; }

}

public School(string name, int enrolment)

{

_name = name;

_enrolment = enrolment;

}

public int CompareTo(object obj)

{

if (obj == null) return 1;

School otherSchool = obj as School;

if(otherSchool != null)

return this._enrolment.CompareTo(otherSchool._enrolment);

else

throw new ArgumentException("Object is not a School");

}

class SchoolMinEnroll

{

static void Main()

{

int numSchools = 5;

School[] schools = new School[numSchools];

Console.WriteLine("Enter data for {0} schools\n", numSchools);

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

{

Console.Write(" School #{0} -> Name : ", i + 1);

string name = Console.ReadLine();

Console.Write(" School #{0} -> Enrolment : ", i + 1);

int enrolment = int.Parse(Console.ReadLine());

schools[i] = new School(name, enrolment);

Console.WriteLine();

}

Array.Sort(schools);

Console.WriteLine("\nThe schools sorted by enrolment are\n");

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

{

Console.WriteLine(" Name : {0, -16} Enrolment : {1, 4}",

schools[i].Name, schools[i].Enrolment);

}

Console.Write("\nEnter minimum enrolment : ");

int min = int.Parse(Console.ReadLine());

Console.WriteLine();

if (schools[numSchools - 1].Enrolment < min)

Console.WriteLine("There are no schools with an enrolment of that level");

else

{

Console.WriteLine("The schools with an enrolment of at least that level are\n");

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

{

if (schools[i].Enrolment >= min)

{

Console.WriteLine(" Name : {0, -16} Enrolment : {1, 4}",

schools[i].Name, schools[i].Enrolment);

}

Console.ReadKey();

}
