10 is an even number

Example 2:

using System;
					
public class Program
{
	public static void Main()
	{
		int a = 20, b = 10;

		if (a > b)
		{
			Console.WriteLine("a is greater than b");
		}
		
		if (a < b)
		{
			Console.WriteLine("a is less than b");
		}        
		
		if (a == b)
		{
			Console.WriteLine("a is equal to b");
		}
