Question

C# Design and implement a program (name it PalindromeInteger), to check if an integer value is a palindrome or not, using 2 methods (reverse and isPalindrome) specified as follows: Method reverse(int number) takes integer number and returns number in reverse order. The method mathematically reverses the number. Method isPalindrome(int number) takes integer number and returns true if the number is palindrome; false otherwise. Use method reverse() to implement method isPalindrome(). Notice that an integer value is palindrome if the value and its reverse are equal. In the main method, prompt the user to enter an integer value and the program should display proper judgment whether the input value is palindrome or not. Document your code and properly label the input prompts and the outputs as shown below.

Answer 1

using System;

public class PalindromeInteger
{
    public static int reverse(int number)
    {
        int temp = 0;
        while (number > 0)
        {
            temp *= 10;
            temp += (number % 10);
            number /= 10;
        }

        return temp;
    }
    
    public static bool isPalindrome(int number)
    {
        return number == reverse(number);
    }
    
    public static void Main(string[] args)
    {
        Console.Write("Enter a number: ");
        int number = Convert.ToInt32(Console.ReadLine());
        Console.WriteLine("Entered value: " + number);
        if (isPalindrome(number))
        {
            Console.WriteLine("Judgment: Palindrome");
        }
        else
        {
            Console.WriteLine("Judgment: Not palindrome");
        }
    }
}
