While loop

Hi guys,

I am new here and my journey with programming has just started. I need help with while loop in C#. Could anyone help with coding this using while or for loop?
it should count from 1 to 100 and prints out every number in the sequence that is divisible by 5 and tests whether that integer is even or odd.
Thanks,
Kasit

Do you mean evenly divisible by 5 since every number is technically divisible by 5

Yes I mean divisible by 5 the number has to be an integer so it would have to be 5,10, 15 etc until 100.

Thank you,

Re: While loop

try this, and i'm not sure if this will work 100% since i havent compiled it

int i = 1;

while(i <= 100)

{

     if(i % 5 = 0)

     {

          Console.writeLine(i);

               if(i % 2 = 0)

                    Console.writeLine(i + "is even");

               else

                    Console.writeLine(i + "is odd");

     }



     i++;



}

again, i might be wrong about some of that since i didnt compile it, and can't compile it because i dont have an IDE on my comp right now.

Re: While loop

Mangle it a little bit and call it pseudocode. Then no one can bust your chops. ;)

using System;

using System.Collections.Generic;

using System.Text;



namespace ConsoleApplication1

{

    class Program

    {

        static void Main(string[] args)

        {



               private bool isDivisibleBy(int checkItem, int divItem)

        {

            if (checkItem % divItem == 0)

                return true;

            return false;

        }

            {

            int i = 1;

            while (i <= 100)

         



      



                if (isDivisibleBy(i, 5))

                {

                    if (isDivisibleBy(i, 2))

                        Console.WriteLine(i + " - even");

                    else

                        Console.WriteLine(i + " - odd");



                    {

                        Console.writeLine(i);

                        if (i % 2 = 0)

                            Console.writeLine(i + "is even");

                        else

                            Console.writeLine(i + "is odd");

                    }



                    i++;



                }

            }

have done it like that but still isnt working, any hints?

Re: While loop

Please wrap the code in [code] My code [/code ] tags !
Oh, and do tell what the problem is with the code.

Re: While loop

I agree with xavier, we need to know what problem your getting so we can take a look.
