displaying even and odd number

Ahmet Taha

Hello Guyz coiudl anyone help me? the output should be like this

Enter Number : 10

The even number is : 2 4 6 8 10

The Odd number is 3 5 7 9

here is my code:

int x;
Console.Write("Input Number:\t");
int num = Convert.ToInt32(Console.ReadLine());
for (x = 0; x < num; x++)
{
    if (x % 2 == 0)
    {
        Console.Write(" ");

    }
    else
    {

        //Console.Write("\n");
        Console.Write("{0}", x);
    }
}

try this
static void Main(string[] args)
       {
           int number     = 0;
           Console.Write("Input Number:\t");
           number = Convert.ToInt32(Console.ReadLine());
           Console.WriteLine("Even Numbers :");
           for (i = 1; i <= number; i++)
           {
               if( i%2 == 0 )
               {
                   Console.Write(i + " ");
               }
           }

           Console.WriteLine("\nOdd Numbers :");
           for (i = 1; i <= number; i++)
           {
               if (i % 2 != 0)
               {
                   Console.Write(i + " ");
               }
           }

           Console.WriteLine();
       }

Console.Write("EVEN NUMBERS \n");

for(a = 1; a <= num; a++)

1. using System;
3. class RecExercise6
4. {
5. public static void Main()
6. {
7. int n;
8. Console.Write("\n\n Recursion : Print even or odd numbers in a given range :\n");
9. Console.Write("-------------------------------------------------------------\n");
11. Console.Write(" Input the range to print starting from 1 : ");
12. n = Convert.ToInt32(Console.ReadLine());
14. Console.WriteLine("\n All even numbers from 1 to {0} are : ", n);
15. EvenAndOdd(2, n);//call the function EvenAndOdd for even numbers
17. Console.WriteLine("\n\n All odd numbers from 1 to {0} are : ", n);
18. EvenAndOdd(1, n);// call the function EvenAndOdd for odd numbers
19. Console.WriteLine("\n\n");
21. return ;
22. }
23. static void EvenAndOdd(int stVal, int n)
24. {
25. if(stVal > n)
26. return ;
27. Console.Write(" {0} ", stVal);
28. EvenAndOdd(stVal+2, n);//calling the function EvenAndOdd itself recursively

Console.WriteLine("Input number");
var line = Console.ReadLine();
var number = int.Parse(line);
var evens = new List<int>();
var odds = new List<int>();
for (var i = 1; i <= number; i++)
{
if (i % 2 == 0)
{
evens.Add(i);
}
else
{
odds.Add(i);
}
}
Console.WriteLine($"The even number is : {string.Join(',', evens)}");
Console.WriteLine($"The odd number is : {string.Join(',', odds)}");
