C# program to reverse a number

Here in this post we are going to learn how to reverse a number using C#.Net

What is reverse a number:

If user enters the number 12345, and if we reverse this number we will get 54321 as a reversed number.

So here 12345 is a number entered by user and 54321 is a reversed number.

What can we cover in this program:

1. we will ask user to enter a number on the console

2. we will read the number entered by the use and reverse that number

3. we will print the enter number and reversed number on the console

Reverse number program:

Code Snippet 1
using System;

namespace AlgorithamsAndLogics
    class ReverseNumber
        static void Main(string[] args)
            Console.WriteLine("Please enter a number to reverse!");
            int number = Convert.ToInt32(Console.ReadLine());
            int tempnumber = number;
            int reverseNumber = 0;
            while (tempnumber > 0)
                var remainder = tempnumber % 10;
                reverseNumber = reverseNumber * 10 + remainder;
                tempnumber = tempnumber / 10;
            Console.WriteLine($"Actual number: {number}");
            Console.WriteLine($"Reversed number: {reverseNumber}");



Happy coding..!
