Program To Check The Number Is Palindrome Or Not

A Palindromic number or numeral Palindrome is a number, which remains the same when its digits are reversed. Like 16461, for example, it is “symmetrical”. The term palindromic is derived from Palindrome, which refers to a word (such as rotor or racecar) whose spelling is unchanged when its letters are reversed.

Example 
  1. class Program {  
  2.     static void Main(string[] args) {  
  3.         int num, rem, sum = 0, temp;  
  4.         //clrscr();    
  5.         Console.WriteLine("\n >>>> To Find a Number is Palindrome or not <<<< ");  
  6.         Console.Write("\n Enter a number: ");  
  7.         num = Convert.ToInt32(Console.ReadLine());  
  8.         temp = num;  
  9.         while (num > 0) {  
  10.             rem = num % 10; //for getting remainder by dividing with 10    
  11.             num = num / 10; //for getting quotient by dividing with 10    
  12.             sum = sum * 10 + rem;  
  13.             /*multiplying the sum with 10 and adding  
  14.             remainder*/  
  15.         }  
  16.         Console.WriteLine("\n The Reversed Number is: {0} \n", sum);  
  17.         if (temp == sum) //checking whether the reversed number is equal to entered number    
  18.         {  
  19.             Console.WriteLine("\n Number is Palindrome \n\n");  
  20.         } else {  
  21.             Console.WriteLine("\n Number is not a palindrome \n\n");  
  22.         }  
  23.         Console.ReadLine();  
  24.     }  
  25. }
