C# Program to Reverse a Number

This is a C# Program to get a number and display the number with its reverse.

This C# Program Gets a Number and Display the Number with its Reverse.

Here we obtain a number from the user and display the digits in the reverse order.

Here is source code of the C# Program to Get a Number and Display the Number with its Reverse. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

    class Program
    {
        static void Main(string[] args)
        {
            int num, reverse = 0;
            Console.WriteLine("Enter a Number : ");
            num = int.Parse(Console.ReadLine());
            while (num != 0)
            {
                reverse = reverse * 10;
                reverse = reverse + num % 10;
                num = num / 10;
            }
            Console.WriteLine("Reverse of Entered Number is : "+reverse);
            Console.ReadLine();
 
        }
    }
}

In this C# program, we are reading the number using ‘num’ variable. Multiply the value of ‘reverse’ variable by 10 and add this value of reverse variable with the modulus of the value of ‘reverse’ variable by 10. Compute the division of the value of ‘num’ variable by 10. Print the number with its reverse order.

 
Enter a Number : 123
Reverse of Entered Number : 321
