A palindrome number is a number that is same after reverse. For example 121, 34543, 343, 131, 48984 are the palindrome numbers.

Palindrome number algorithm

Get the number from user
Hold the number in temporary variable
Reverse the number
Compare the temporary number with reversed number
If both numbers are same, print palindrome number
Else print not palindrome number

Let's see the palindrome program in C#. In this program, we will get an input from the user and check whether number is palindrome or not.

Program Code

using System;  
  public class PalindromeExample  
   {  
     public static void Main(string[] args)  
      {  
          int n,r,sum=0,temp;    
          Console.Write("Enter the Number: ");   
          n = int.Parse(Console.ReadLine());  
          temp=n;      
          while(n>0)      
          {      
           r=n%10;      
           sum=(sum*10)+r;      
           n=n/10;      
          }      
          if(temp==sum)      
           Console.Write("Number is Palindrome.");      
          else      
           Console.Write("Number is not Palindrome");     
    }  
  }

Output

Output 1:
Enter the Number=121   
Number is Palindrome.

Output 2:
Enter the number=113  
Number is not Palindrome.

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
