In this blog, we will write a C# program to reverse a number.
Reverse a Number in C# Code
First it reverses a number. This code sample shows youhow to reverse a number in C# .
  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5. using System.Threading.Tasks;
  6. namespace Reverse_Number {
  7. class Program {
  8. static void Main(string[] args) {
  9. int num, temp, remainder, reverse = 0;
  10. Console.WriteLine("Enter an integer \n");
  11. num = int.Parse(Console.ReadLine());
  12. temp = num;
  13. while (num > 0) {
  14. remainder = num % 10;
  15. reverse = reverse * 10 + remainder;
  16. num /= 10;
  17. }
  18. Console.WriteLine("Given number is = {0}", temp);
  19. Console.WriteLine("Its reverse is = {0}", reverse);
  20. Console.ReadLine();
  21. }
  22. }
  23. }
Now run the Reverse Number Code
Click On Start button
Open the debug console panel
Output the Reverse a Number Code
I hope you understood how to Reverse a Number using C# Code.
