collections in c#(list of prgmming lang)

Create a list of programming languages and do the following actions:

a)check whether the list contains the language "C#" in it.
b)if there is a language 'c' in the list, then remove it.
c)add the language "vb.net" to the 4th position of the list
d)sort the list
e)display the list

Try this:

using System;

using System.Collections.Generic;

class Program

{

static void Main()

{

List languages = new List

{

"C",

"C++",

"C#",

"Objective-c",

"Java",

"Smalltalk",

"Javascript",

"Python",

"Ruby",

"PHP",

"Fortran",

"Cobol",

"Pascal",

"F#",

"Haskell"

};

if (languages.Contains("C#"))

{

Console.WriteLine("C# is contained in the list");

}

else

{

Console.WriteLine("C# is not contained in the list");

}

if (languages.Contains("C"))

{

languages.Remove("C");

Console.WriteLine("C has been removed from the list");

}

languages.Insert(3, "VB.Net");

Console.WriteLine("VB.Net has been inserted at position 4 (index 3) in the list");

languages.Sort();

Console.WriteLine("The list has been sorted into alphabetical order");

Console.WriteLine("\nThe languages in alphabetical order are\n");

foreach(string language in languages) Console.WriteLine(language);

Console.ReadKey();

}

Try this:

using System;
using System.Collections.Generic;

class Program
{
static void Main()
{
List languages = new List
{
"C",
"C++",
"C#",
"Objective-c",
"Java",
"Smalltalk",
"Javascript",
"Python",
"Ruby",
"PHP",
"Fortran",
"Cobol",
"Pascal",
"F#",
"Haskell"
};

if (languages.Contains("C#"))
{
Console.WriteLine("C# is contained in the list");
}
else
{
Console.WriteLine("C# is not contained in the list");
}

if (languages.Contains("C"))
{
languages.Remove("C");
Console.WriteLine("C has been removed from the list");
}

languages.Insert(3, "VB.Net");
Console.WriteLine("VB.Net has been inserted at position 4 (index 3) in the list");

languages.Sort();
Console.WriteLine("The list has been sorted into alphabetical order");

Console.WriteLine("\nThe languages in alphabetical order are\n");
foreach(string language in languages) Console.WriteLine(language);

Console.ReadKey();
}
}
