Palindrome program in C#

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.

1. using System;
2.   public class PalindromeExample
3.    {
4.      public static void Main(string[] args)
5.       {
6.           int n,r,sum=0,temp;
7.           Console.Write("Enter the Number: ");
9.           temp=n;
10.           while(n>0)
11.           {
12.            r=n%10;
13.            sum=(sum*10)+r;
14.            n=n/10;
15.           }
16.           if(temp==sum)
17.            Console.Write("Number is Palindrome.");
18.           else
19.            Console.Write("Number is not Palindrome");
20.     }
21.   }

Output:

```Enter the Number=121
Number is Palindrome.
```
```Enter the number=113
Number is not Palindrome.```
