Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.Simple_program
{
    class Simple3   //Print even and odd number upto n
    {
        static void Main(string[] args)
        {
            Console.Write("Enter a number upto which you want to print even and odd number: ");
            int n = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine();

            Console.WriteLine("-----Output-----");

            Console.WriteLine();
            Console.WriteLine("Even number upto: {0} are: ", n);

            for (int i = 1; i <= n; i++)
            {
                if (i % 2 == 0)
                {
                    Console.Write(i + " ");
                }
            }

            Console.WriteLine();
            Console.WriteLine();
            Console.WriteLine("Odd number upto: {0} are: ", n);

            for (int i = 1; i <= n; i++)
            {
                if (i % 2 != 0)
                {
                    Console.Write(i + " ");
                }
            }

            Console.WriteLine();
            Console.ReadKey();
        }
    }
}

Output:
The input number here is 20. So, the program will print even and odd number separately upto 20. The output is shown below:

Enter a number upto which you want to print even and odd number:
20

Even number upto: 20 are:
2 4 6 8 10 12 14 16 18 20
Odd number upto: 20 are:
1 3 5 7 9 11 13 15 17 19
