Application of Reverse number

Ques: Write a program where user gives two inputs digit , the program  reverse the inputs and add them and again reverse there sum.

  For Exp: 

Input:
Enter first number: 56
Enter second number:89

Output:
reverse of first number: 65
reverse of second number:98

sum of two reverse no is: 163

reverse of sum: 361


Source Code:

1. using System;  
2.  
3. public class SumOfDigit   
4. {  
5.     public static void Main()  
6.     {  
7.         int number1, number2;  
8.         int sum=0;  
9.   
10.         Console.Write("Enter the first Number: ");  
11.         number1=Convert.ToInt32( Console.ReadLine() );  
12.   
13.         Console.WriteLine("Reverse of first Number: {0}\n", ReverseNumber( number1 ));        
14.   
15.         Console.Write("Enter the second Number: ");  
16.         number2=Convert.ToInt32( Console.ReadLine() );  
17.   
18.         Console.WriteLine("Reverse of second Number: {0}\n", ReverseNumber( number2 ));  
19.   
20.         sum = ReverseNumber( number1 )+ReverseNumber( number2 );  
21.   
22.         Console.WriteLine("\n\nSum of Two reverse number is: \t{0}", sum);  
23.   
24.         sum = ReverseNumber( (ReverseNumber( number1 )) + (ReverseNumber( number2 )) );  
25.         Console.WriteLine("Reverse of sum of Two number is: \t{0}",sum);  
26.     }  
27. 
    
28.     public static int ReverseNumber( int digit )  
29.  
30.     {  
31.         int x,reverse=0;  
32.           
33.         while(digit !=0)  
34.         {  
35.             x=digit%10;  
36.             reverse=reverse*10+x;  
37.             digit=digit/10;  
38.         }  
39.         return (reverse);  
40.     }  
41. }

Note: we can also optimize the code by adding a variable reverseSum and store the value of reverse of sum (Line-29) in it.
