Code:

using System;

using System.Collections.Generic;

using System.Text;

/*Lesson 2 : Loops,

 * Loops are a great way to make things easier for your application for example

 * if you want to increment a number (1) to 100 you normally would have to either do this

 * lets say i is our integer and i = 1

 * you would have to do this    i++ or i + 1; to increment it by one 

 * instead you could use a loop!

 * here is a basic do- while loop i don't like them too much but heres an Example:

 * int i = 1;

 * do {

 * i++;

 * }while( i != 100);

 * 

 * now what i generally use a for loop

 * for(int i =1; i != 100; i++)

 * {

 * //code here to either display whats happening or do something a certain amountof times

 * }

 * 

 * 

 * Loops that you can break out of:

 * These are useful loops i shouldn't have to explain how they are useful if you have the mind set of a programmer

 * For this loop i will use it to determine what numbers are even

 */

namespace Loops // namespace declaration

{

    class Program   //class declaration

    {

        static void Main(string[] args)//iniates the program

        {

            Console.WriteLine("Enter in your number:");// Prompts the user 

            int n_ = Convert.ToInt32(Console.ReadLine());//iniates a variable named _n makes it able to input text by converting string to int

            for (double e = 0; e != Convert.ToInt64(n_); e++)// the start of your for loop! declares your variable there was no need to convert i just wanted it to hold bigger numbers then increments by one for each loop

            {// what is inside your loop

                if (e % 2 == 1)// if (variable e modulus 2 = 1 ) continue with operation

                    continue;

                if (e == n_)//if(variable e reaches the stopping point n_ break;

                    break ;

                Console.Write("{0} ", e);//writes your even variables

            }//closes loop

            Console.ReadLine();//pauses it

        }

    }

}

I also included everything in the .rar file this tutorial shows you along with loops I/O and how to see if a number is even or odd using the Modulus operator Feedback questions post below also what should my next tutorial be?

This is good tut, it is interesting how while loops in pascal and c# are the same but c# has "do while" and pascal "repeat until" !
You could make a comparation between pascal and c# . . . but it is okay this way.
And another suggestion, make something with 2 loops (one inside of another) !
And break & continue operations are good . . . and also declaring variables inside a for loop !

haha can do lesson 2
More advanced loops i think they're called nested loops though
