Write a C# program to check if a number is divisible by 2

To check if a number is divisible by2 or not, you need to first find the remainder.

If the remainder of the number when it is divided by 2 is 0, then it would be divisible by 2.

Let’s say our number is 10, we will check it using the following if-else −

// checking if the number is divisible by 2 or not
if (num % 2 == 0) {
   Console.WriteLine("Divisible by 2 ");
} else {
   Console.WriteLine("Not divisible by 2");
}

The following is an example to find whether the number is divisible by 2 or not −

Example

 Live Demo

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Demo {
   class MyApplication {
         static void Main(string[] args) {
         int num;
         num = 10;

         // checking if the number is divisible by 2 or not
         if (num % 2 == 0) {
            Console.WriteLine("Divisible by 2 ");
         } else {
            Console.WriteLine("Not divisible by 2");
         }
         Console.ReadLine();
      }
   }
}

Output

Divisible by 2
