Visual Presentation:
Sample Solution:
C# Sharp Code:
using System; // Importing necessary namespace
public class Exercise37 // Declaration of the Exercise37 class
{
public static void Main() // Main method, entry point of the program
{
int num, r, sum = 0, t; // Declaration of variables
Console.Write("\n\n"); // Displaying new lines
Console.Write("Display the number in reverse order:\n"); // Displaying the purpose of the program
Console.Write("--------------------------------------\n\n"); // Displaying a separator and new lines
Console.Write("Input a number: "); // Prompting the user to input a number
num = Convert.ToInt32(Console.ReadLine()); // Reading the number entered by the user
for (t = num; t != 0; t = t / 10) // Loop to reverse the number
{
r = t % 10; // Extracting the last digit of the number
sum = sum * 10 + r; // Reversing the number by storing each digit sequentially
}
Console.Write("The number in reverse order is : {0} \n", sum); // Displaying the number in reverse order
}
}
Sample Output:
Display the number in reverse order: -------------------------------------- Input a number: 25 The number in reverse order is : 52
