c# how to write an if statement code example

Example 1: c# if statement

using System;
namespace DecisionMaking 
{
   class Program 
   {
      static void Main(string[] args) 
      {
         /* local variable definition */
         int a = 10;
        
         /* check the boolean condition using if statement */
         if (a < 20) 
         {
            /* if condition is true then print the following */
            Console.WriteLine("a is less than " + a); //output: a is less than 20
         }
         Console.ReadLine();
      }
   }
}

Example 2: c# if else

using System;

namespace DecisionMaking 
{
   class Program 
   {
      static void Main(string[] args) 
      {
         /* local variable definition */
         int a = 100;
         int b = 20
         
         /* check the boolean condition */
         if (a < b) 
         {
            /* if condition is true then print the following */
            Console.WriteLine("a is less than " + b);
         } 
        else 
         {
            /* if condition is false then print the following */
            Console.WriteLine("a is not less than " + b);
         }
         Console.ReadLine();
      }
   }
}
                       =======OUTPUT========
output >> a is not less than 20
